Rugged Environment Thermostats

Dramm single and two stage mechanical thermostats offer unmatched, rugged control of greenhouse temperatures. Built for durability, accuracy and reliability, Dramm Mechanical Thermostat can be flexibly wired to be used in multiple situations.

Inaccurate thermostats result in greater heating and cooling costs!


Prepare your greenhouse for summer heat with a thermostat upgrade from Dramm. No more rusted metal boxes with hand-marked calibration.

Single Stage Thermostat


The Dramm Microfan mechanical thermostats are designed with rough environments in mind. These high quality thermostats are perfect for any situation where harsh conditions may damage less durable equipment. Protected in sealed PVC housings, these thermostats offer stainless steel coiled sensors and accuracy to 1_ C. The SPDT (Single Pole Double Throw) switch contact (one set of contacts open on temperature rise as the other set closes) is a no load contact and offers superior accuracy.

Designed to be placed in the area to be controlled, the Dramm Microfan Thermostats are perfect for heating, cooling, and ventilation control in greenhouses, factory buildings, warehouses, farms or anywhere requiring accuracy in control.

Two different thermostats are available: the T41-SV Single-Stage and the T42-SV Double-Stage Thermostat. Both are CSA approved and available in Canada.
