MINIB Trench Heaters

The MINIB units are offered where higher outputs are required or a fan assisted unit is preferable. Stainless steel casings including heat exchangers (and fans, as required) are built in to the floor at the exposed locations. These locations are usually large glazed areas (such as glazed curtain walls, french windows and doors in showrooms, houses, flats, conservatories, swimming pools etc.) In addition to the principal of their work, which is heating, floor convectors also serve as heat screens at cold windows to increase thermal comfort in interiors.

MINIB units are supplied in a range of standard sizes, ready assembled for ease of installation. Units are complete with stainless steel casings, heat exchangers, fans (where applicable), flexible connectors and shut off valves as standard. Fan assisted units can achieve duties up to 3100W/m based on 82/71 water 18 EAT. Units are also available to offer cooling during the summer. Tables below show duties for a sample of the fan assisted range of trench heaters including the new 50mm deep T50 unit.
