UB20 In-Line Heating System Designed for Emergency Shelters

RAMFAN’s UB20 In-Line Heating System is a propane-fired portable heating system that provides safe, warm air into emergency shelters and confined spaces.

The heater’s stainless steel heat-exchanger ensures the supplied air is not contaminated with fuel or exhaust from combustion. It is compatible with common propane tanks. A standard 20lb tank can provide up to 10 hours of continuous heating.

UB20 Blower/Exhauster
Explosion-proof blower/exhauster is manufactured to meet the requirements of the ATEX Directive, IEC standards and INMETRO standards. Safely blow or exhaust hazardous gases with minimal risk of the fan causing a spark.

Safety is compromised if any component along the electrical path in the blower/exhauster poses a risk of igniting a spark. Therefore, the UB20xx is built using only certified explosion- proof components along the electrical path.

Furthermore, once assembled the whole unit is certified for safe use in explosive atmospheres in accordance with the limitations of the rating. It is the user’s responsibility to determine the suitability of equipment for the intended purpose.In addition to providing peace of mind to the user, whole-unit certified fan prevents suppliers from being linked to the chain of liability.

That is why it is crucial for users and suppliers to demand whole-unit certification.
