Grieve Installs Combination Airflow Jumbo Walk-In Oven

30 April 2008

Grieve has installed an electrically-heated, 350ºF (~176ºC) jumbo combination walk-in oven, used for curing composite parts at their customer’s facility.

Workspace dimensions measure 10’W x 40’D x 8’H. 160KW are installed in Incoloy sheathed tubular elements to heat the unit, while two 20-HP recirculating blowers with total 49,500 CFM capacity provide combination airflow to the load.

This Grieve oven features 4” insulated walls throughout, removable top-mounted heat chamber (shown removed in photo), aluminized steel interior and exterior, front and rear double doors with air-operated opening assist plus an 8” x 10” double pane Pyrex window in each door, 1/4” thick plate floor and four interior oven lights. The unit was split into six sections for installation clearance at the customer’s factory.

The oven is equipped with all safety equipment for handling flammable solvents, including explosion venting door hardware, 2600CFM powered forced exhauster and motorized dampers on intake and exhaust for accelerated cooling. The unit is built to NEMA 12 electrical standards.

Controls on this Grieve jumbo combination walk-in oven include a digital programming temperature controller, strip chart recorder, SCR power controller and ten digital countdown timers.
