PRODUCT DATA COMFORT CT300/POLAR BY NILAN Ventilation & passive heat recovery Passive heat recovery

COMFORT CT300/POLAR Product description Based on the many years’ experience from the Comfort series, Nilan has developed a future-proof system, Comfort CT300, that meets the 2020 requirements of ventilation systems, and is also passive-house certified. The unit is constructed to ensure low energy consumption by optimising the air flows in the system and thereby reducing the internal pressure loss, as well as using quality components with low energy consumption. We have thereby developed an energy-efficient ventilation system with heat recovery for homes and smaller commercial buildings with...

Can be connected to an external water or electrical pre-heating element Time controlled alarm for filter change. Easy filter access - the top front panel manually unscrews easily. There is plenty of space to replace filters and vacuum the filter space. Visual alarm for filter change. 100 % automatic bypass function that carries the air past the counterflow heat exchanger when heat recovery is not required. Aluzinc steel plate, white powder coating (RAL9016) Efficient counterflow heat exchanger providing high temperature efficiencey and low pressure loss, resulting in good heat recovery and...

PLANNING DATA Nilan units are tested in accordance with the valid standards of accredited independent test institutes. Capacity Capacity of standard unit as a function of qv and Pt, ext. SEL values according to EN 13141-7 are for standard units with ISO Coarse >90% (G4) filters and without heating element. SEL values comprise the unit´s total power comsumption incl. control. Conversion factor: Attention! The SEL values are measured and stated as a total value for both fans. Pt ext [Pa] 400 350 300 250 Temperature efficiency Temperature efficiency for units with counterflow heat exchanger...

Sound data Sound output level (LWA) Octave band Hz Sound output level LWA drops with falling air volume and falling back pressure. Sound data for qV = 171 m3/h and Pt, ext = 100 Pa according to EN 9614-2 for surfaces and EN 5136 for ducts. Sound output level LpA at a given distance will depend on acoustic conditions in the place of installation.

OPERATION Intelligent humidity control Nilan’s humidity control automatically adapts to the needs of inhabitants or the building itself. Immediately change in % of RH The intelligent CTS400 / CTS602 control unit does not require a set air humidity level (RH) to manage the air exchange. Using the integrated humidity sensor, the control unit calculates the average humidity over the past 24 hours and regulates the air flow accordingly. Consequently the unit’s efficiency is based on actual instead of theoretical air humidity levels. Forced ventilation Reduced ventilation Normal ventilation...

Capacity - Heating element (accessory) Electrical heating element The electrical heating element is fitted in the supply air duct at a distance of min. 2 x duct diameter from the system´s fresh air connection pipe (normally min 320 mm.) and connected to the CTS400 / CTS602 control panel and 230 V supply. The electrical heating element can supply up to 1,2 kW of heat. Water heating element for duct fitting The water heating element is designed to be built into the duct and must be connected to the primary heating supply and the CTS400 / CTS602 control. The water heating element includes...

CTS400 is a simple and intuitive control panel with a complex control system that contains many useful functions. On the control panel you can set the fan speed level, turn the unit on and off and see potential alarms. When installed in rental properties, hotels etc., you can lock the panel so tenants cannot turn off the unit and/or alter the fan speed level. The many functions of the control system enable you to connect, for instance, afterheating elements and a CO2 or VOC sensor. The control system includes, as standard, user selection programs, an intelligent humidity control system and...

PC-Tool Nilan provides a PC tool for creating settings and for balancing the unit. This gets installed in the installer’s computer. Via a USB connection on the outside of the unit it is then connected to the circuit board for the unit. The selected settings can be saved to the installer’s computer and can be copied to another unit where the same settings are required. If necessary, PC Tool also allows the installer to update the software in the unit. The user has no access to alter the settings via PC Tool. Nilan User APP By purchasing a Nilan gateway, the user can gain access to the unit...

AUTOMATION CTS602 CTS602 Control The CTS602 HMI touch panel is featuring a wide range of functions, e.g., menu-controlled operation, weekly programme settings, filter monitor with timer, fan speed adjustment, summer bypass (free cooling), supply-heating element control, error messages etc. The CTS602 comes with factory settings, including a default setting which can be customised to operational requirements to achieve optimum operation and utilisation of the system. There is an option for selecting between 2 front page images for the main screen. Operating instructions for the CTS 602 can...

Functions overview Description of errors indicated with alarms. Alarm log displaying the latest 16 alarms. Joint alarm The CTS602 control system has an output signal that is activated in the case of an alarm. It can be connected to, for example, external automation.
