Air cooled condensing and casters are standard.


Conditioning

Conditioned chamber air is recirculated by a high volume, non sparking aluminum axial fan discharging through a removable rear mounted guard and diffuser baffle to create a uniform environment around your test objects.

The fan is driven by a close coupled externally mounted motor with dual ball bearing races, connected by a 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

All systems have thermal and current sensors on the compressor, charging valves, 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.

Power requirement is 115 VAC - 1 Phase – 60 Hertz, 25 FLA. Refrigeration is air cooled. 50 Hertz is available as an option.


Construction

FB1.5V Series chambers include a 304 Series stainless steel welded inner 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 dual gaskets to greatly reduce thermal losses near the door face. An over-center, black anodized aluminum cam type latch seals the door which closes flush on the front face of the chamber for a smooth appearance.


Controls

Each Bemco FB1.5V chamber is furnished with a microprocessor based programmable 1/4-DIN, solid state, 10 step ramping controller that utilizes an adaptive control algorithm to precisely control chamber temperature.

The control features dual 4 digit displays. An advanced control algorithm improves sensor accuracy by more than 50%. Temperature inside the FB1.5V chamber is sensed by a precision thermocouple. An EIA-485 Modbus interface is standard.


Thermal Performance

Cooling rate from 23 C (+73 F) to -73 C (-100 F) is approximately 45 minutes and heating rate from 23 C (+73 F) to +177 C (350 F) is approximately 35 minutes, both with the chamber empty.

+ or - 1 C (+ or - 1.8 F) guaranteed control, + or - 0.15 C (+ or - 0.25 F) typical.


Optional Equipment

Optional Instruments

Controls are mounted on a recessed aluminum panel to prevent dripping from damaging the instruments. Available instrument accessories:
