york air-conditioning products Activa rooftop details & features PCB board Condenser fan New condenser fans with high technology blades and outdoor bell that reduce the turbulences in the air and therefore increase the efficiency and improve the noise level performance. Tandem scroll compressors Tandem compressors configuration allows the unit to operate at partial load (only with one compressor) with higher efficiency and increases the working range up to +52°C ambient temperature.
Air Systems Energy recovery system It is the preferred solution to solve two conflicting requirements: reduce running costs (increase efficiency) while maintaining the indoor air quality at high levels (through ventilation). An enthalpy rotary wheel retains the energy from the exhaust air and transmits it to the fresh air stream that is being supplied in the conditioned space. The material used is manufactured with the latest technology to increase the energy transmission in both sensible and latent heat.

york air-conditioning products Accessories & options Triple input economizer Indoor air quality This system utilizes 3 probes: Return Air, Outdoor Air and Supply Air. The Outdoor Air damper and the Return Air dampers are mechanically interconnected in order to provide the same airflow at the coil inlet, with a single damper motor. The PCB compares sensor values and modulates the dampers providing maximum efficiency of the economiser system (free cooling) and comfort (Supply Air > 12°C).
Air Systems Fixed and adjustable roof curbs Hot water coil with control Ideal for down-flow applications, it is a great help for installation allowing duct connections, electrical connection and weatherproofing between the roofcurb and the roof of the building. Shipped in kit form, it also gives sufficient height for condensate trap operation. The hot water coil and his control are always fitted, wired and factory tested.
york air-conditioning products Design details Cabinet features • Build to last, all cabinet with heavy gauge galvanized steel and powder paint backed on oven. • Copper-copper coils or blue fin delivered upon request. • Side or bottom duct connections to be realized on site. • Excellent water-tightness even with high internal negative pressure. • External slopes to remove rain water. • Only 4 solid points to crane.
Air Systems Control System YKN2open The YKlon is a controller regulating all components and accessories. It will pro actively manage cool and heat stages to maintain a stable room temperature maximizing the efficiency. Additionally, the benefits are: • Redundancy on cool and heat stages (if one step is locked out, the PCB starts another one automatically). • Random start between units to minimise electrical tariff. • All stages will start in sequence to reduce peak inrush.
