Model HF4-2, High Performance Horizontal Airflow Benchtop Oven, Two Shelves, 4.9 Cu.Ft. (also: model 1670)
SHEL LAB High Performance Ovens are engineered to meet the most critical temperature requirements. They are designed for continuous drying operations at temperatures up to 260°C. Factory-set overtemperature protection prevents control failure from damaging contents and guards against burnout. The Watlow controller provides a 24-step ramp and soak, 0.1°C control, multiple levels of operator access and automatic resumption of program following a power failure. Time and temperature are displayed in a three-digit LED readout for fast and accurate setting. In addition, the sealed membrane touch-pad control panel is water and acid resistant.
Horizontal air flow provides fast heat-up and recovery and ensures rapid drying. Heated air is continuously circulated by twin turbo blowers. Blowers also circulate air to motor bearings to prolong motor life. Punched stainless steel shelves are adjustable on 1/2 inch centers. Adjustable three air intake and exhaust ports can be opened for fast drying of high-moisture content samples. The 3.5 inch thick wrap-around fiberglass insulation on all sides minimizes heat loss.
A high temperature gasket door seal eliminates air leakage and ensures longer gasket life while being subjected to extreme operational temperatures. This unit includes long-lasting, low-watt density heating elements. It also has adjustable heavy-duty hinges and a door latch that are designed for lifetime service.
The HF4 has rugged, welded construction with a double-walled, corrosion-resistant stainless steel interior and a powder-coated exterior.
