About Us

MJB Controls specialises in the design, manufacture and MJB Controls About Usdistribution of quality Air Conditioning and Refrigeration control equipment.


MJB Controls began life supplying electrical switchgear to OEM's of HVAC/R. It wasn't long before the need to provide more specialised control products arose. Timers were added to the range followed soon after by Defrost Controls, Air Conditioning Control systems, Thermostats and Zone Controls which are manufactured in Sydney.


The range has continued over the years to grow adding programmable wired and wireless thermostats, temperature and humidity controls as well as phase failure rotation relays amongst many other products.


The future will bring yet more new products to the quality range on offer, like Soft Starters, Variable Frequency Drives, Fan Speed Controls and Touch Screen Thermostats.
