Notus Units NOTUS units are designed as compact heat recovery ventilators to meet the increasing demand for energy efficiency by means of heat recovery and energy consumption for residential and commercial HVAC applications. The units are equipped with the latest technology components and IQ control system. Applying the latest developments in components, NOTUS units ensure very low specific fan power (SFP) values and high heat exchange efficiencies. With the standard IQ control and LCD control panel the user can select between different operational modes, independent 3 speed fan speed control, unbalanced ventilation, weekly timer, filter monitoring, free cooling by means of “By-pass Ventilation” and automatic fan speed setting with “Ventilation on Demand”.
Functions NOTUS units: • • • • •
Supply fresh air for indoors. Extract stale indoor air. Transfer heat between supply and exhaust air streams. Filters supply air. Reheats fresh air with hot water coils.
Energy Savings and Environmental Responsibility With their superior heat recovery potential, an average size NOTUS unit is capable of recovering approx. 15 kW of heat energy per hour in winter with nominal air flows. On an annual basis, it is possible to recover over 65000 kW of thermal energy in certain climatic conditions. To generate this thermal energy the atmosphere would be subject to 13000 kg of CO2 emissions with natural gas. At Impelair AS we encourage such benefits in order to preserve the natural heritage for future generations.

Casing
NOTUS units have by-pass ventilation as standard. With bypass ventilation it is possible to use fresh air directly to cool indoors in the summer. The controller checks both indoor and outdoor air temperatures and user set temperature and switches on/ off the clamp integrated directly to the unit.
50 mm Mineral wool insulated panels are used in NOTUS units. The panels comprises of externally painted galvanized sheet metal and internally galvanized sheet metal. Appropriate gaskets are used to block heat and air leakage. The service doors are delivered with lockable latches.
Higher Energy Efficiency and Reduced Energy Consumption With the optimised heat exchanger, fans and other components the overall energy consumption of the unit is reduced by up to 20% compared to its ancestors. With the unique design of the heat exchanger and fans, NOTUS units ensure the highest level of energy efficiency for residential ventilation applications.
Greater Flexibility NOTUS units are equipped with the latest technology components and control system. Counterflow heat exchangers are used to increase the heat transfer in the heat recovery exchanger. NOTUS units are available with both aluminum and polystyrene heat exchangers. With polystyrene heat exchangers it is possible to extend heat recovery efficiency to up to 95% because of the unique structure of the air ducts inside the heat exchanger.
Enhanced Filtration Standard NOTUS units are equipped with G4 class filtration with 90% dust arrestance performance. F6 or F7 class filtration for fresh air is also available as an option. Control NOTUS units are equipped with IQ control. IQ control is capable of controlling EC fans, by-pass clamp, frost heater and operation timer. Fans can be controlled using three speed settings/unbalanced ventilation/ventilation on demand or constant flow. Two permanent temperature sensors measure return air/fresh air temperatures and control the by-pass. Filters are checked with a timer and the user is reminded when to carry out filter maintenance periodically. Optional total control is also available.

Compact Design
Low Sound Level
Notus units are designed for easy transport and installation. The maximum width of the unit does not exceed 900 mm and the maximum height is 1900 mm. With these specifications the unit can be transported and moved on the field easily.
With the innovative RadiCal blade design and the lower pressure drop of both components and internal design, the sound level of the unit is reduced along with the reduced fan speed. Thanks to the unique casing design, NOTUS units have high sound absorption character, reducing the radiated sound levels.

Components Heat Exchanger Counterflow heat exchangers are used to increase the heat transfer in the heat recover exchanger. NOTUS units are available with both aluminum and polystyrene heat exchangers. With polystyrene heat exchangers it is possible to extend heat recovery efficiency to up to 96% because of the unique structure of the air ducts inside the heat exchanger. The triangular ducts in the polystyrene heat exchanger of NOTUS are arranged so that each one is surrounded by separate parallel ducts in which the air stream flow is in a "counterflow" flow pattern. This maximizes the heat transfer surface area and increases heat exchange efficiency. To decrease the pressure drop across the heat exchanger the dimensions are optimised in both aluminum and polystyrene heat exchangers.

Fans can be controlled using three speed settings/unbalanced ventilation/ventilation on demand or constant flow. Two permanent temperature sensors measure return air/fresh air temperatures and control the by-pass. Filters are checked with a timer and the user is reminded when to carry out filter maintenance periodically. By-Pass By-pass ventilation is used during summer and allows return air to by-pass the heat exchanger, thereby introducing fresh air at outdoor air temperature and cooling down indoors. NOTUS units are equipped with by-pass ventilation as standard. With the pre-installed temperature sensors IQ control checks return air temperature, fresh air temperature and user set temperature. According to the evaluation in the PCB, the bypass clamp is opened automatically. Warm Climate

Filters Panel filters are used in NOTUS Units for standard filtration. The filtration class is G4 according to EN 779. G4 filters are medium efficiency disposable air filters suitable for ventilation applications with good dust-holding capacity. The filters consist of a dry non-woven extended surface fabric medium and create low initial pressure drop. For higher filtration demand NOTUS Units have extra filtration as an option. Extra filters are class F6 or F7 according to EN 779 and used to fine-filter fresh air. The filters consist of a non-flammable fabric medium which is pleated to extend the filtration surface and decrease the pressure drop. The pleated filter mediumis contained within the air filter by a rigid all cardboard casing. 11
Accessories Heating Despite the high thermal efficiency, to increase the supply air temperature in winter optional heating coils are available for NOTUS units. For heating fluid, steam or hot water is used. The coils are carefully engineered for an optimum balance between air side pressure drop and heat transfer coefficient. The coils are made of specially corrugated Aluminum fins and copper tubes. The fin spacing is limited to a minimum of 2,1 mm for easy cleaning and maintenance. Heating coil capacity is controlled by means of a modulating control valve and user set temperature. The modulating valve is integrated into NOTUS’s Total Control system.
Cooling Cooling coils (water or direct expansion) are available as optional equipment for NOTUS units. With cooling coils it is possible to cool down the supply air by means of chilled water or refrigerant removing both sensible and latent heat from fresh air. The coils are carefully engineered for an optimum balance between air side pressure drop and heat transfer coefficient. The coils are made of specially corrugated Aluminum fins and copper tubes. The fin spacing is limited to a minimum of 2,5 mm for easy cleaning and maintenance. To help the flow of the condensed water drops on the coil surface, the fins are coated with a special phenolic material. Cooling coil capacity is controlled by means of a modulating control valve and user set temperature. The modulating valve is integrated into NOTUS Total Control system. Droplet eliminators are used as standard with cooling coils in NOTUS units. A double slopped condensation tray made of stainless steel are used to drain condensed water. A siphon system made of ABS is delivered along with the units.
Fresh Air heater Electric or water driven coils are available for extreme climates for freeze protection. A freeze thermostat with a free contact is delivered with the coils to activate the circulation pump or start the electrical resistance elements. For water coils a glycol-water mix must be used.

Accessories Total Control NOTUS units are optionally available with the state of art “Total Control”. Total Control is a complete solution for the control of NOTUS units and delivered optionally with the units. It comprehends the latest technologies in communication and design, replacing the traditional hard-wired “on-site” solutions. All system configuration and site applications are performed by user friendly Web Interface that eases installation and commisioning work. The system includes all components required for controlling fans, electric and hydronic heating coils, cooling systems, drives for rotary heat exchangers and actuators in modern air handling units. The system components communicate via state-of-art bus technology while external communication is handled via standard bus systems required by the market. The master contains a high-performance processor unit and all interfaces into and out of the system.

Accessories Constant Flow Kit NOTUS units are equipped with EC fan controllers and differential pressure transmitters. The pressure transmitter monitors the pressure change in the fan inlet ring and calculates the air flow automatically. After the installation the user can set the air flow demand from the NOTUS Hand Terminal or the PC Interface and the Greentech EC fans will regulate the fan speed according to the set air flow. Eliminating the changes in pressure drop inside the unit (filters and other equipment) and in the duct system, NOTUS units will run with the design air flow as a result of the state of art Total Control.
Ventilation on Demand By use of additional CO2 /IAQ or RH sensor the demand indoors is calculated and the fan speed settings are adjusted accordingly. To switch to VOD mode, a proper sensor must be installed and connected, to the duct system and also the user must select “VOD” on Select Mode menu of the Remote Control. When VOD (Ventilation On Demand) is selected the fan speed is controlled by the analog 0-10V input signal.
Pressure Switch / Indicator NOTUS units are optionally available with visual pressure indicators and/or pressure switches. When the pre-set pressure difference is reached within the filters a generic alarm is generated from the Total Control and the user is warned for filter service.
