Details

Puravent are the UK mainland distributor for Mark Climate Technology.

We offer the GS+ range of gas-fired, high performance air heater with an axial fan. This condensing equipment provides efficiency greater than 106% (lower value). Heat is generated via a modulating premix burner 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 (available soon).

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.

Average The Room Is A Normal Residential Room, Office, Reception Area Or Similar, Where There Is Not Overly Crowded With People, Computer And Office Equipment.
Above Average There Are Factors That Contribute To Additional Heat Being Generated In The Room E.G. Strong Lighting, Overcrowding With People And Office Equipment, Conservatory Type Room, Or Flat Roofed Room.
High There Are Factors That Contribute To A High Heat Load In The Room. E.G. Commercial Cooking, Much Computer And Server Equipment, Switchgear, Temporary Building With Thin Walls And Flat Room, Plain Glass Conservatory.
