Trellsystem is an inflatable self-supported, highly adaptable combat support hospital system designed for operating in chemical warfare environments.
Trellsystem provides inhabitants with an encapsulated environment that seals against chemical invasion, thus affording protection from gases and aerosols. The system also features protection against chemical liquid infiltration by shrouding the tents with a chemical fly.
The hospital tents can be connected together to provide continuous formations with no loss to the integrity of the environment. The interior environment is over-pressured by filtered air and is climate controlled using heaters and air condition units.
The Fan Unit is made if high gauge steel containing a radial fan driven by a motor. The Unit is used to re-circulate clean through either the AC-unit ACUTE 75C, or through the heater Unit, VACAN 100.
The control unit incorporates a control box with all equipment necessary to monitor and control the environment during a C-attack. The over-pressure can be monitored on a pressure gauge easily visible on top of the unit.
Designed for heating and ventilation of tentage in a C-environment.
The heater is placed outside the tent with master controls inside the tent. In summer time the unit can operate as a ventilation unit. The unit can also operate as a stand-alone heater. Capacity of the unit is 100,000 BTUs (35kW)
The air conditioner consists of a compressor/condenser unit. It is made from high gauge steel with all its components protected from damage during transport and in usage. Temperature adjustment is achieved via a thermostat. The construction surrounding the condenser is specially made for C-environment. The unit can be fitted with a heating element. The AC-unit can be utilized as a stand-alone unit in a non-chemical threat environments. Capacity of the AC units is 75,000 BTUs (24kW).
the Filter Unit is constructed of sheet metal and is complete with carrying handles. The C-filter consists of a fan unit, cyclone, particle filter and an activated charcoal filter type ASC 12-30 TDKA. The inlet air first passes through a cyclone, removing larger particles before the second stage, fine particle filter. After all solids are removed C-contaminated air passes through a charcoal filter, removing all hazardous gases before entering the tent unit. The filter can be used without the charcoal filter. The system is then operated as an ordinary over-pressure system.
