Electric Heater Batteries, electric vent heaters, industrial heater batteries and electric heaters for the heating and ventilation trade
We at Mercian are specialist manufacturers of electric air heaters for the air conditioning & process heating industries. We also supply electric heater batteries and industrial heater batteries.
All of our heaters are specifically designed to operate at Low Surface Temperatures (below 400 °C), giving each heater a very long working life and safe operation.
As a safety feature, every electric heater is fitted with a high temperature thermal trip to shut down the unit in the event of fan failure or low airflow situations. These thermal trips may be manual or auto-resetting to suit the application.
Two heating methods are utilised...
1. ELECTRICAL RESISTANCE WIRE
Spirals of Chromium resistance wire, wound to an exact load, are supported within ceramic formers and energised to give a very accurately controlled heat output. This system has the added advantage of a rapid heating/cooling response from the elements.
2. INCOLOY 800 STAINLESS STEEL SHEATHED ELEMENTS
Sheathed elements are our most popular heating method and are usd to meet the property Service Agency "M&E100" specifications. Large numbers of elements can be banked together to give loadings of up to 400 kilowatts with a variable number of stages. This type of heater meets the British Standards and gives a superior working life and added safety.
