Typical configuration for users suitable for closed circuits
Typical configuration for users suitable for open circuit
The below diagram shows a typical closed circuit lay-out. Pressurised closed circuit applications (5) always require an expansion vessel. TAEevo Tech units in standard (evaporator in tank) configurations are ideal for such applications, and offer a pressurised automatic fill kit including the expansion tank (as option).
The below diagram shows a typical open circuit lay-out. For atmospheric circuit applications featuring an open tank (4), the water is in contact with the ambient air, as such no expansion vessel is required. Such applications are suited to TAEevo Tech units in standard (evaporator in tank) configuration but without the tank kit and pump, given that the system typically features an external pump (2).

TAEevo LASER
R407C
Air-cooled chillers for Laser applications, with R407C equipped scroll or piston compressors. Cooling capacity 17,5 - 90,2 kW.
Non-ferrous water circuit
Well specified hydraulic circuit
The increasing complexity of the laser sources necessitate the use of cooling fluids with an ever greater purity level. TAEevo Laser’s non-ferrous water circuit is suited to operation with demineralised water containing additives. The tank, plate evaporator and high head pressure centrifugal pump are all in stainless steel, and protect the laser source from all forms of contamination.
• Non-ferrous design, allows the use of demineralised water containing additives; • Stainless steel centrifugal multistage pump, including an outlet manometer; • Heating element to maintain the process fluid above the dewpoint, minimizing condensation risks; • Stainless steel atmospheric pressure accumulation tank with integrated drain valve; • Hydraulic circuit fill tank with externally visible water level; • Stainless steel brazed plate evaporator with manual bleed and drain valves; • Electronic level sensor with water conductivity function.
A plug-and-play solution TAEevo Laser always operates, whatever the conditions, thanks to shut-off valves, an adjustable internal by-pass valve, a 43 °C ambient temperature limit, an antifreeze protection and a self-regulating level sensor. Installation is notably simplified thanks to the integration of all components within the unit itself, an IP54 protection rating and the easy transportability of the unit itself.
Robust and reliable A robust frame and components from renowned suppliers, including reliable scroll compressors (models 081-351), ensure absolute peace of mind. Advanced safety devices ensure stable and safe operation, including a heater immersed in the tank (to avoid condensation on the laser’s optics), and an antifreeze function which activates the heater and starts the pump (for stable operation). Metallic condenser pre-filters are mounted as standard. All the units are equipped with a phase monitor which provides protection against phase loss and phase reversal. All the scroll compressors are equipped with crankcase heater as standard.
Easy to use and maintain The sophisticated laser equipment installed within a continuous production cycle needs to be backed up by chillers which are both absolutely reliable and very easy to maintain. MTA’s TAEevo Laser allows the chiller to be serviced even whilst it continues to operate normally, notably reducing downtimes. Easy access is ensured, thanks to the application of removable panels and access doors.

AQUAFREE Add-on Freecooling modules for Aries tech, Galaxy tech and Phoenix plus, transforming the Chiller into an all-in-one modular and expandable Freecooling Chiller. Cooling capacity 242 - 466 kW per single module.
Plug & Play
Peace Of Mind
Connect AquaFree to the chiller (AST, GLT and PNP) and set the software parameters comunications between the units. The chiller’s xDRIVE microprocessor will control the chiller / free-cooler combination as a single unit. In case of AQUAfree connection to a chiller previously installed check before the software compability. The AQUAfree / chiller piping kit is available on request.
Each AquaFree module features its own microprocessor, allowing it to operate independently. If one module suffers a fault the others can still operate, if the chiller suffers a fault the modules can continue to operate. AquaFree can operate at ambient temperatures of -15 °C to +46 °C. Each AquaFree module features independent aeraulic sections featuring axial fans with progressive activation (continuos control on request).
Energy Efficient
Versatile
AquaFree can easily obtain savings of 30% or more, offering efficiency levels well beyond the industry norm. The modular design permits additional AquaFree modules to be added, allowing efficiencies to be further increased and tailored to individual applications.
As AquaFree modules are independent, so system transportation is simplified. AquaFree can be positioned separately if space needs dictate it. It is also possible to install AquaFree, or add additional modules, at a later date. Each AquaFree module features its own remote on/off control.
Super Silent
Models & Versions
Choose between 2 noise levels, both extremely quiet, with an electronic fan speed control option to further reduce part load noise levels. Especially during night time, when temperatures drop and freecooling becomes more active, AquaFree’s low noise becomes a notable asset.
• Acoustic versions: - N - basic acoustic configuration; - SN - low noise acoustic configuration; • Modules: - AFW100 (for connection to AST 090-140); - AFV200 (for connection to GLT/PNP); - AFV300 (for connection to GLT/PNP); • Low ambient air temperature - down to -20 °C.
Indipendent Each module features its own electrical connection and 3-way valve, as well as its own electrical panel and microprocessor with independent alarms and water in/out and ambient temperature visualization: consequently each module can operate completely autonomously.
Glycol Free Kit The kit is available on request and is ideal in applications requiring an absence of glycol, such as food and plastics industries. The kit features its own intermediate exchanger and an hydraulic circuit, is simply installed between the chiller and the AquaFree modules.

Tailor made Free-Cooling
Select your efficiency
AquaFree allows the user to define the desired efficiency, simply combining multiple modules to achieve the optimum freecooling level. Any combination of AFV200 and AFV300 modules allows the freecooling section to be increased one “V” coil at a time from a minimum of two coils upwards.
The size and number of AquaFree modules applied allows the efficiency level to be progressively increased from Basic (N) to Efficient (E) and even High efficiency (HE) levels.
Total Freecooling Temp. (°C)
As an example, a GLT150N chiller, operating at water 15/10 °C with 30% glycol and a single AFV300 module (Basic “N” configuration), achieves a TFT (total freecooling temperature), the temperature at which the unit achieves 100% freecooling) of -0,2 °C). Alternatively, the application of two AFV200 modules (Efficient “E” configuration) achieves a TFT of +3,1 °C. By applying an AFV300 module and an AFV200 module (High efficiency “HE” configuration), a TFT of +5,0 °C can be achieved.

RWD Air-cooled liquid coolers. Cooling capacities 10 - 372 kW.
An environment-friendly solution
Versions
RWD liquid coolers, with finned coils and axial fans, are the ideal solution for the free-cooling of applications in which the process temperature is higher than the ambient temperature for most of the year. Exploiting low ambient air temperatures, RWD cools the fluid free of charge, eliminating energy wastages caused by running refrigerant compressors during winter.
• Acoustic versions: - C (standard); - SC (low noise); - SSC (very low noise).
Free-cooling In new plants customers can select the RWD model which provides the ideal compromise between installation cost and return on investment. In the case of existing plants retrofitting an RWD equipped with a 3-way valve in series with the system chiller is a viable solution. Installation of an RWD not only increases the life of the chiller, but also allows significant energy saving levels ensuring a return on the initial investment in approximately twelve months.
Plug and play From RWD 200 the main components such as 3-way valves, manifolds, and single or double pumps can be installed in the unit. RWD can be installed outdoors thanks to the IP54 protection rating and epoxy surface coating of the frame. Consequently no time is lost in component selection and RWD installation is rendered quick and easy.

(1) Values refer to standard units at the following operating conditions: ∆T 10 °C between water inlet temperature and ambient temperature, ∆T 5 °C between water inlet temperature and water temperature at outlet from chiller located at sea level and with 0% glycol. (2) Model RWD 020 is available also in a version for connection to a 400V±10%/3/50Hz power supply. (3) Sound pressure level in hemispherical field at 10 m from condenser side and 1.6 m from ground. Values with tollerance ± 2 dB. The sound levels refer to operation of the unit under full load in nominal conditions.
Reduced costs, reduced environmental impact
Airbatc version
Cooling towers suffer substantial costs due to the treatment of the process water. Because it uses a closed circuit, RWD does not require any form of process fluid treatment and eliminates liquid losses caused by evaporation.
The RWD Airbatic version, thanks to the water sprayed on the cooling coils, offers the following benefits: • The chilled water at the outlet can be at a temperature which is below ambient temperature; • High cooling capacity within compact dimensions; • Low water consumption compared to cooling towers; • Radical energy savings when cooling the condensation water for watercooled chillers; • High cooling power in presence of high ambient temperatures; • High cooling efficiency also in the low noise operating mode..
Microprocessor controller RWD units can be equipped with a microprocessor featuring an intuitive graphic interface. The controller manages the fans independently, starting them in steps in proportion to the fluid inlet temperature.

CLICK AND CHECK xCONNECT, MTA’s world of connectivity solutions, allows connection to User-supplied Building Management Systems (BMS), connection via local LAN or Ethernet networks, connection to MTA’s dedicated xWEB supervisor, the possibility to program or download storical data via USB connection, and much more beyond. Serial connection to the most advanced BMS systems allows MTA units to be integrated into a centralised supervisor through ModBus protocol. The integration with Lonworks, Bacnet, Profibus system is possible through apposite gateways (not included). Local supervision via intranet or internet can also be achieved via Ethernet, with pre-programmed HTML supervision pages which, according to the unit type, are already pre-programmed within the unit itself. Local Ethernet connection allows multiple units to be interconnected within an autonomous system, with one unit acting as Master. The User can manage all units within the system via the Master unit, or via a remote User interface.
