LEEC reach in and walk in rooms are designed and built using experience gained in over 50 years of temperature control. LEEC rooms will meet very high performance criteria at a competitive price. Temperature stability performance of better than ±1°C and a humidity control of ±3% are typical.
All rooms are constructed from interlocking insulated panels incorporating polyurethane foam insulation of between 60mm and 100mm thickness, dependant on the specification requirements. These panels meet or exceed European specifications for 'fire retardation' and 'surface spread of flames'.
Floors are normally insulated and given a non-slip finish for safety. Specialist finishes are also available. Some applications can be specified without an insulated floor.
Interal and external wall surfaces are usually of corrosion resistant steel finished in a food safe plastic laminate. Stainless steel is recommended when the room is to be humidified or possibly exposed to potentially corrosive vapours.
Hinged doors have an external lock and an internal safety release mechanism. Sliding doors can also be fitted to larger rooms.
Rooms with operating control from -20°C to above +60°C have all been successfully installed. Incubator rooms typically have temperature control to better than 1°C.
Microprocessor controllers automatically call for heating or cooling only as required, in order to achieve optimum temperature stability with maximum operating efficiency. (This is in marked contrast to other systems which constantly overcool and then have to add excessive heating power in order to achieve the required temperature).
