GC+ air heater

Custom made environment friendly

In addition to the high efficiency air heater, the Mark range also includes a gas-fired, high performance air heater with a centrifugal fan. The GC+ is particularly suited for connection to duct systems, or systems where high pressure is required. This condensing equipment provides efficiency greater than 106% (lower value). Heat is generated via a modulating (5:1) premix burner which results in very low gas consumption.

The GC+ is operated using an Optitherm+ clock thermostat or an Interface+ module that allows a connection with the BMS (building management system) via Modbus or a 0-10V contact. The Optitherm+ also makes it possible to control the GC+ units remotely with an app for mobile phone and tablet (available soon). Other operating options are also available.

An extensive range of additional sections has been developed for the GC+. This ensures the standard GC+ can be simply and affordably adapted to any project specification. The comprehensive capacity range (35-150 kW) also means the area of application for this type of equipment is virtually limitless. The GC+ can additionally be incorporated into an air handling unit. The GC+ is designed to heat garages, warehouses, workshops, schools and sports halls among other applications, with or without a duct system.
