This small, cost-effective industrial safety oven meets NFPA Bulletin 86 requirements for handling solvents and expelling hazardous vapor. Ideal for industrial safety oven applications such as flash curing paint samples, drying solvents, curing epoxies or adhesives. This industrial safety oven is also useful in laboratories which require a variety of product loads.
CSP Industrial Safety Oven Operating Range
Temperature range: +10°C above ambient to +343°C (+650°F)
Temperature uniformity: 1.5% of setpoint after stabilization with exhaust
Control accuracy: 0.25% of setpoint
Rugged Industrial Safety Oven Construction
The industrial safety oven exterior and door are built from heavy gauge, cold rolled reinforced steel. The oven interior is lined with Type 304 stainless steel. All interior seams are heli-arc welded vapor tight preventing fume infiltration into the oven's insulated walls. The door is sealed around its entire perimeter using a tubular silicone rubber gasket.
Reliable Industrial Safety Oven Heating Elements
Industrial oven air is heated by an Eternal ' an open wire resistance heating element designed and manufactured by Blue M . A solid state power relay controls the heater from a signal from the STAT-190011.
Volatile Fume Exhaust System
The CSP-400 industrial safety oven is equipped with a powered exhaust system to remove fumes from the oven interior. An exhaust blower provides up to 90 cfm to power this exhaust function. The control signal to the air heater is interlocked with the airflow switch such that the heaters will not operate unless the powered exhaust is functioning.
Safety Relief Panel
A blowout relief panel is installed in the rear wall of the oven work space. This feature relieves any rapid increase in interior pressure that might result during the processing of solvents. The blowout panel ruptures during a fault in pressure condition, venting the oven interior. The ruptured panel is contained by a perforated metal cage mounted on the back wall of the oven.
Advanced Controls
The CSP-400 industrial safety oven employs a STAT190011 control system. This single loop temperature controller features a bright LED display that shows setpoint, oven temperature, control output, etc. during oven operation. Indicator LEDs on the controller face log alarms and control output status during oven operation. All control functions are accessed using three large keys on the controller face, guided by prompts from the control display. The STAT-190011 monitors oven air temperature using a sheathed Type J thermocouple, located in the oven work space. Hardware and software interlocks prevent accidental data loss or change.
Safety Purge Timer
A purge timer circuit is included in the STAT-190011 control system to provide a fresh air purge of the oven interior. The purge timer circuit is reset/started by opening and closing the oven door. The purge timer allows the powered exhaust and recirculating blowers, to run for a preset interval, flooding the oven with fresh air to remove built up volatile fumes. The purge circuit is interlocked with the oven air heater to prevent the heater from running during the purge cycle.
Independent Over-temperature Protection
Part of the STAT-1900® control system is the TempLimit® over-temperature control. This is a 1/4 DIN FM approved electronic control with an independent sheathed Type J thermocouple sensor. This device provides overtemperature protection, and is standard with the STAT-1900® control system. When oven temperature exceeds the selected operating limit, the air heater is turned off, an audible alarm sounds and a panel mounted indicator light is lit. Manual reset is required to restore normal oven operation.
Flexible Product Loading
Wire rod shelves are available for use in the CSP-400 industrial safety oven. There is a maximum of seven (7) shelf positions. Shelves are available in either nickel plated or stainless steel. Stainless steel is recommended for greater strength and cleanliness. Adjustable brackets for each shelf are included.
