4 and 5-Roller Oven - OFITE

The OFITE Roller Oven (U.S. Patent No. 4,677,843) is an effective aid in determining the effects temperature has on drilling fluid as it circulates through the wellbore. Aging the drilling fluid in pressurized containers effectively demonstrates the thermal effects on viscosity and how various additives behave at elevated temperatures. Aging is done under conditions that vary from static to dynamic and from ambient to highly elevated temperatures. The OFITE 4 and 5-roller ovens are ideal for laboratory use. The OFITE portable oven is specifically designed for field use. OFITE rollers are variable-speed controlled and constructed of stainless steel for longer life and a cleaner environment inside the oven.

Glass impregnated Teflon^® roller bearings extend the life of the rollers and allow for longer maintenance-free service. All models feature a digital temperature controller that can be read directly from outside the oven. The temperature is controlled by an electronic solid state thermostat and operates between 100°F and 450°F (38°C - 232°C). The 4 and 5-roller ovens are provided with a seven-day programmable timer as standard equipment. The timer may be preset to automatically start and stop the heaters, thus avoiding the need for an operator to be in attendance during off hours. A circulation fan motor gives you greater control over the temperature inside the oven while the optional redundant heat control kit provides an important safety mechanism. Both options are available on the 4 and 5-roller ovens.
