Controlling SWD Heaters
Thermostatic control is highly recommended. The simplest option is to select a heater with the prefix SWD-A. This indicates that a built-in adjustable thermostat is provided. The built-in thermostat has a set-point range between 5°C and 30°C and includes a frost protection setting.
Where remote thermostatic control is preferred we recommend our tamperproof Hard Case Range of Electronic Control Devices (see below). Hard Case thermostats’ tamperproof design ensures that only authorised personnel can adjust the temperature setting. The standard Hard Case is not waterproof, however the Hard Case range includes an optional remote sensor with an IP55 rating. The Hard Case HC-T2 will switch a single phase load of up to 16A and larger loads or 3-phase loads via a suitably rated contactor.
Safety Guards
Where personnel have access to an SWD heater, the use of an SWG safety guard is strongly recommended. Manufactured from heavy gauge zinc plated wire, the SWG comes complete with mounting clips for easy fixing to floor or wall.
