Thermolier Unit Heater (Steam Fed) single phase. 123L-S-H-1

The distinctive Thermolier Steam-fed Unit Heaters are fan driven, hot air heating system products, which utilise heat exchange technology to transfer heat from steam to the air, keeping costs at bay. Front louvers and careful situation of the units gives exceptionally fast warm up and practical heat control in high roofed, large spaces. Requiring little or no maintenance, this system is tough and efficient.

There are 5 standard size horizontal airflow models in the range, each size available with a either single phase or 3 phase motor. The 3 phase variants have flameproof motors as standard. If you require variation from the standard i.e. vertical down-flow models stainless steel build, please contact our sales team who will be happy to help.

The rated heat outputs (kW) is based on 3 Bar of Steam pressure and entering air temperature of 20°C. For other performance points with other condition parameters the down load 'Thermolier performance table' at the foot of this page should be your guide.
