For "Code D," above, Exterior Height, add approximately 10 inches near the rear of the workspace for fan motors for the F27 and F64. All standard systems except the F64 have air cooled condensing on the refrigeration systems. F64 chambers have water cooled refrigeration systems.


Conditioning

F8 InteriorChamber air is recirculated by a high volume, stainless steel axial fan discharging through a hinged rear mounted guard and diffuser baffle to create a uniform environment around your test objects.

The fan is driven by a vertically mounted motor with dual ball bearing races, connected by a large diameter extended stainless steel shaft. Fast-response open type heaters, located behind a radiation baffle, raise chamber temperature as required.



Cooling, Wide Range

A proportionally controlled cascade, two compressor, refrigeration system utilizing modern environmentally friendly refrigerants cools the workspace. The system includes automatic hot gas bypass and suction cooling unloading as well as Bemco’s exclusive, high performance coaxial cascade heat exchanger.


Cooling, Narrow Range

A proportionally controlled single compressor refrigeration system utilizing a modern environmentally friendly refrigerant cools the workspace. The system includes automatic hot gas bypass and suction cooling unloading.


Safety Systems and Electrical Wiring

F27 Chamber All systems have thermal and current sensors on the compressor, charging valves, and a sight glass as well as numerous safety and reliability protection systems for dependable operation. All electrical wiring meets the United States National Electric Code. UL and CSA approved components are used where possible.

An F27 model is shown. Notice that the the controls are located on the right side to prevent dripping on the control instruments when the door is opened


Construction

All F Series chambers include a 304 Series stainless steel welded liner with high temperature fiberglass insulation. No asbestos is used in chamber construction. Outer cases are fabricated from cold rolled steel finished in Bemco Blue. Chamber doors feature Bemco’s plug door to minimize problems with expansion and contraction on the door face and dual gaskets to greatly reduce thermal losses near the door face. An over-center Bemco cam-type latch seals the door.


Controls

Each Bemco chamber is furnished with a microprocessor based, programmable 1/4-DIN, solid state 256-step ramping controller which includes a 4-line LCD interface display and a large red LED display.

Temperature inside the chamber is sensed by a precision thermocouple. An RS232 and RS485 interface is standard. Heaters are interlocked with a separate heavy duty power contactor and a factory preset high temperature safety control.


Thermal Performance

On Narrow Range Chambers (N), cooling rate from 23 C (+73 F) to -35 C (-31 F) is approximately 45 minutes, or 2 C (3.6 F) / minute. Average heating rate from 23 C (+73 F) to +177 C (350 F) is 3.4 C (6.2 F) / minute, both with the chamber empty.

On Wide Range Chambers, cooling rate from 23 C (+73 F) to -73 C (-100 F) is approximately 55 minutes, or 1.7 C (3.2 F) / minute.

Average heating rate from 23 C (+73 F) to +177 C (350 F) is 3.4 C (6.2 F) / minute, both with the chamber empty. + or - 1 C (+ or - 1.8 F) guaranteed control, + or - 0.15 C (+ or - 0.25 F) typical.

Optional Instruments

Controls are mounted on the side or top to prevent dripping from damaging the instruments.
