GS+ natural gas air heater
Gas-fired high performance natural gas air heater with axial fan
Mark manufactures a gas-fired, high-performance natural gas air heater with an axial fan. This condensing equipment provides efficiency greater than 106% (lower value). Heat is generated via a modulating (5:1) premixburner which results in very low gas consumption.
The GS+ 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 GS+ units remotely with an app for mobile phone and tablet.
The GS+ is suitable in many situations due to its extensive capacity range from 13,6 to 142,2 kW. The GS+ is designed to heat garages, warehouses, distribution centres and showrooms.
Mark provides a 2 year full product warranty as standard and up to 10 years reducing warranty with the stainless steel heat exchanger.
