TC540 Heating Thermal Cabinet and TC550 Heating and Cooling Thermal Cabinet Designed for testing samples under predefined temperature conditions, Lloyd Instruments offers a range of thermal cabinets, providing a temperature range from -70°C to 300°C within a large general purpose test area. A high speed centrifugal fan provides rapid air movement within the cabinet allowing rapid temperature cycling with minimal temperature gradients. Visual inspection is made easy thanks to a large triple glazed observation panel. For added versatility thermal cabinets are mounted on wheels, which run on an independent base unit for backwards and forwards movement.This enables normal ambient tests to be carried out by simply sliding the cabinet free from the machine’s crosshead. All thermal cabinets are controlled by a sophisticated temperature control unit, that is housed in a separate control console. The cabinet exterior is a one piece shell manufactured from merlin grey leathergrain PVC pre-coated steel. The cabinet interior is constructed from fully seam welded high grade polished stainless steel and is completely separated from the exterior panels by a thermal break. This minimises conducted heat transfer. The hinged door incorporates a high temperature replaceable silicone rubber gasket, which provides a vapour seal against the chamber liner. A 75 mm (3 in) diameter port is fitted in a central position in the working area of both the top and bottom panels. In addition, the cabinet is provided with a 20 mm (0.8 in) diameter cable entry and pressure equalisation port. On models fitted with a cooling option (TC550), the spent cooling gas is vented by an exhaust outlet at the rear of the cabinet, which is connected to a suitable hose for dispersion to atmosphere.
