The New Snow Switch Pro Series Snow & Ice Controls

The Snow Switch GF Pro and PD Pro Controls.

The GF Pro and PD Pro both work with the same field proven sensors that have been used for decades with other Snow Switch controls, the APS and EUR control panels. When used with up to two compatible sensors, the GF Pro and PD Pro automatically control snow and ice melting systems for minimum energy costs.  

• GF Pro Snow & Ice Control with Integral GFEP
• 200 - 277 VAC, 30 amps resistive, 30 mA GFEP

•  PD Pro Snow & Ice Control for Pilot Duty Applications
• 120 VAC, 7 amps inductive, 30 Amps resisitive

About Us

The world today depends on highly reliable systems to provide communications, transportation, power distribution, and security. The forces of nature conspire against these systems in the form of rain, snow, ice, changes in pressure and temperature, wind, dust and more. Moisture and dust can find their way into essential components such as waveguide or electrical enclosures. Snow and ice coat antennas, buildings, roads, bridges, and railways. If allowed to have its way, nature hampers or even destroys the systems we count on.

Environmental Technology,Inc. designs and manufactures products for effectively managing the environment. From energy efficient snow melting and deicing to pressurization systems for satellite and microwave transmission lines, we have 40 years of experience as an industry leader in developing and delivering effective environmental management systems. Environmental Technology, Inc. has the experience you can count on.

Thad Jones. CEO, Founder, Chairman.

Thaddeus M. Jones formed Environmental Technology, Inc. in 1968 and began producing the first Snow Switch^® sensing and control products for commercial deicing. Thad has since been awarded over 60 patents for technologies used in snow and ice detection, condensate and humidity control, ground fault and arc detection, energy management, power distribution, and air pressurization systems. An inventor and consulting engineer at heart, Thad and his team continue to seek out new ways to limit the effects of Mother Nature on communications, transportation, business and safety around the world.

The APS C Series, the top of the line SnowSwitch sensors and controls.

Snow Switch Sensors & Controls

The Environmental Technology Snow Switch line of  snow/ice sensors and controls have provided over 40 years of dependability and experience.

Systems up to 16 amps typically use an LCD–7 controller, integrating sensing and power switching for cost effective deicing of small applications.

Larger systems will use a CIT–1 aerial sensor in conjunction with an APS C series control panel and may include one or more SC–40C satellite contactors. Each APS–4C control panel and SC–40C satellite contactor includes integral ground fault detection and can switch up to 50 amps of direct heater load.

ADH NETCOM Automatic Air Dehydrator

 ADH Automatic Air Dehydrators

The ADH line of automatic air dehydrators has a successful history of delivering pressurized dry air for telecommunication antenna pressurization systems since 1986 and is considered one of Environmental Technology’s premier product lines. This is evident with thousands of units in the field today and the number of units still in service since the product line’s inception. Many of the first units shipped are still in service today more than 20 years later.
