Heater for Instrument Box

Instrument protection boxes used by EHT engineering offer different standards and sizes of enclosure box options to protect field-installed instruments.
The protection boxes are made of a special high-performance glass fibre reinforced polyester (GRP).
This fire-resistant material is extremely tough and highly resistant to damage from chemical and petrochemical environments. It has strength nearly equal to stainless steel and is only one-fourth the weight.

Instrument Box Heaters with EHT Engineering

Safe, Efficient and Smart Heating Solutions for Sensitive Measurement Devices in Harsh Environments

Measurement and control instruments used in industrial facilities are critical to process accuracy and safety. However, these devices are highly sensitive to external environmental conditions. Low temperatures, humidity, the risk of freezing, and sudden temperature changes can negatively impact instrument performance and lifespan. At EHT Engineering, we offer safe and long-lasting solutions specifically designed for industrial sites with Instrument Box Heaters, which we developed to eliminate these risks and maintain measurement accuracy.

What is an Instrument Box Heater?

An instrument enclosure heater is an electrical heating system integrated into the protective enclosures housing field-type measuring instruments. This system maintains the temperature within a specific range, preventing the instruments from freezing, condensation, or temperature-related measurement errors. It is typically implemented using self-regulating or constant-power resistance cables and controlled by thermostats.

Heating systems offered by EHT Engineering can be integrated into new enclosures or retrofitted into existing ones. Each solution is designed specifically for the site's environmental conditions and the type of equipment.
