can get contamination from a build-up of greases and fail due to blockages. These controllers can also be fitted with e-stops around your Kitchen to disable the gas in case of emergency.

To complement the above we also can supply a more technical system which can operated more than one fan this is more common where you have Fresh air fans as well as extraction. We can supply a system which is the intelligent answer to gas ventilation inter-locking and environmental control within the catering sector. With its integral gas pressure proving system and tempered air control, it is the most versatile and compact system on the market.

If you want full control and have a complicated system when you need flexibility our intelligent controller are an excellent product, from starting and stopping of the fans to full control of their speed as well as the monitoring of the fans via our patented power monitoring system. Supply air temperature control and gas pressure proving can be added by simply connecting the correct sensor devices and selecting the required operational mode on the controller.

The range is also backed up by our extensive range of ancillary products, such as gas and LPHW valves and actuators through to remote knock-off buttons and freeze protection devices.

We are more than willing to advise you or our onsite electrician on which product to buy from us. Contact us for more information.

Electric fan speed controllers

HWL can supply or supply and fit solutions for your old speed controller we stock most models and can advise on what is best for your system.

When choosing a speed controller there are factors which you will need to identify to come to your choice.

We stock a range of electronic Controllers -

  • Current controllers used to provide speed control of single phase motors where the peak current of the motor does not exceed the rating of the controller. Units are complete with illuminated on / off switch.
  • Voltage controllers used to provide speed control of single phase motors where the peak current of the motor does not exceed the rating of the controller. Units are complete with illuminated on / off switch.
  • Voltage controller which when used with fans fitted with thermal cut-out protection can trip. In the event of the thermal cut-out opening the controller will switch off and the trip indicator will be illuminated. Units are complete with illuminated on / off and start button. The start button must be pressed to start the controller once on / off switch is in the on position.
  • • A transformer voltage controller used to provide five speed step control of single phase or three phase motors where the peak current of the motor does not exceed the rating of the controller. Speed control is via selector switch. Single phase units are complete with illuminated on / off switch.

Other sense controllers which can be used to switch your Gas inner lock on and off this is done by current monitoring. We feel that current monitoring is a far better way of checking the system operation rather than air speed sensors which
