Blue M Ships Class A Safety Oven to Medical Industry

Blue M®, a global industrial and laboratory ovens manufacturer, announced the shipment of a Class A safety oven to the medical industry.

Designed for ease of move-in and installation, this Blue M Class A oven was modified to an overall height of 79” and width of 45” to accommodate the ceiling height and doorway dimensions at the customer’s facility.

The safety oven has a temperature range of 15°C above ambient to 316°C. The temperature is controlled by a Watlow EZ Zone PM controller with advanced PID control algorithm. The controller offers TRU-TUNE™ adaptive control for tighter control and auto-tune for a quick, efficient start up.

The interior chamber has dimensions of a 48" W x 24" D x 48" and is constructed with 304 stainless steel. All of the seams and ports of the interior chamber are Heli-Arc welded vapor tight to prevent fume infiltration and buildup of flammable materials between the chamber walls. The unit includes five (5) 304 stainless steel slotted shelves with rolled fronts for ease of product loading. Each shelf is capable of holding a 75lb product load.

The oven features several safety options. A blowout relief panel is installed in the rear of the oven and is released into a safety retaining cage if the pressure inside the chamber exceeds a predetermined value. A purge timer can be set to provide a minimum of four complete air changes before heaters are energized. A safety door switch automatically shuts off the oven blower system and heating elements when the door is opened. The activation of the door switch also restarts the purge cycle if it happens in the middle of a process cycle. An emergency power-off button allows the operator to easily shut off the equipment in the event of an emergency and an airflow switch shuts off the heating elements in case of a blower system failure.

 “Blue M offers customers the flexibility to request engineered-to-order modifications to our standard oven designs. This Class A oven features custom exterior dimensions to accommodate the customer’s facility ceiling height and doorways. This is the second unit with these special dimensions that this customer has ordered.”
