We customize ovens in various temperature ranges, material of construction and chamber dimensions. Maximum operating temperature range of these ovens are 200°C, 250°C and 300°C, which is controlled through microprocessor based PID controller, which displays both set value (SV) and process value (PV) and plays important role in temperature control.

About the product

We customize ovens in various temperature ranges, material of construction and chamber dimensions. Maximum operating temperature range of these ovens are 200°C, 250°C and 300°C, which is controlled through microprocessor based PID controller, which displays both set value (SV) and process value (PV) and plays important role in temperature control.

Forced air circulation is maintained using branded motor driven blower system. For heating, we use ceramic bead heating elements or tubular air heaters for high temperature. Each unit is fitted with over temperature protection device (safety thermostat), which keeps your oven safe in case of controller failure.

Our hot air oven is having attractive design, rugged construction and easy to clean surface; therefore, internal chamber of our ovens is made of thick gauge of stainless steel (SS 304 / SS 316). Corners are such designed that cleaning becomes an easy job for operator. Shelves are made of stainless-steel wire mesh cable; these are removable in order to adjust the height level. Depending upon size of internal chamber quantity of shelves may vary from 2 to 7 or more. External cabinet is made of either powder coated mild steel, GI sheet or stainless steel as required. For easy mobility of large ovens, caster wheels with brake are fitted at the bottom.

We offer several optional accessories to fit in your hot air oven; such as, explosion proof heater, digital timer, PLC based HMI controller, RS485 computer interface, 21 CFR software, data logger and circular chart recorder, HEPA filter air inlet etc.
