DeltaMaster - For Telecom stations and technical rooms
DeltaMaster is a unique market solution for telecom stations. The function involves a fresh air unit pushing clean air into the room without mixing it. Stratifying the air causes the warm air to rise to the ceiling and then exit through an exhaust grille.
DeltaMaster has a built-in temperature sensor and automatically adjusts fan speed as needed, according to the setpoint values in the included control unit.
AirSite's popular control unit, DeltaManager, is packed with features! In addition to the ability to set values for adjustment and reading, DeltaManager also offers a range of other functions. This includes standard damper control, a log of the latest alarms, a start signal for the cooling machine, more connection options via analog and digital inputs, advanced network functions via Modbus TCP for remote control and monitoring.
Today, we offer DeltaMaster in 48V and 230V versions with cooling capacities* ranging from 2kW to 12kW, with as low a ∆T as 2°C.
DeltaMaster 48EC units are designed for telecom applications with 48V power supply. Our advanced control units regulate the fan continuously and have special modes for fire or power outage. It is also very easy to reprogram the control unit if additional special functions are desired.
DeltaMaster 230EC units are designed for technical rooms with 230V power supply.
We have a comprehensive list of accessories including air heaters, intake hoods, exhaust hoods, damper systems, roof hoods, grilles, communication products for monitoring, and more.
*By cooling capacity, we mean the heat load that the free cooling can ventilate away.
