Infresco Infrared Heating Controllers

Infresco is the market leader in the control of Infrared Heating applications, offering a wide range of discreet and stylish control products to create a ‘State of the Art’ heating system.

The Infrared heating used with our controllers works by instantly heating the objects in its radius, not by heating the great outdoors. This minimises energy costs and waste by only using power when required or by varying heat output levels. Turning itself on when you walk into a designated area, that powers down on a day that is too warm. That is the advantage of Infresco Controllers it will smoothly and silently manage your outdoor heating leaving you to get on with running your business.

Envirostat Frost Protection Controllers

The Envirostat range of electronic thermostats are designed to offer energy efficient frost protection and temperature control to pipe work and trace heating, where thermal insulation alone cannot. Envirostat monitors the temperature and controls it between set temperature ranges.


United Automation is one of the leading manufacturers of products which utilise the soft start and soft stop feature. With the Envirostat Soft Start/Stop feature, the current at switch on and switch off is controlled by a semi-conductor which removes switching transients, this protects the internal switching device and the external supply contactors.
