Air & Gas Heating Solutions by Wisebros

At Wisebros Industrial Solutions Ltd., we provide custom-engineered Duct Heaters for the safe and efficient heating of air and process gases in industrial ventilation and pipeline systems. Our product range includes standard electric duct heaters as well as Ex’d (flameproof) duct heaters designed for use in hazardous environments such as refineries, chemical plants, offshore platforms, and LNG terminals.

Designed for both non-hazardous HVAC systems and Zone 1/Zone 2 classified areas, Wisebros duct heaters are built to deliver uniform heat distribution, low pressure drop, and long operational life. Whether for heating combustion air, process gas, nitrogen, or clean room ventilation streams, our solutions are tailored to meet the exact temperature, flow, and safety requirements of your operation.
