OEM Bitzer Compressor Lab Chiller With -35C~ 140C Temp Controlled


Technical Information

1, technical design requirements:

1. high temperature medium tank temperature range: 50 °C to 140 °C; volume: 240L; heating period ≤ 90 minutes, heating rate 1-2 °C / min;

2. low temperature medium tank temperature range: -40 °C to 30 °C; volume: 240L; cooling cycle ≤ 90 minutes, cooling rate 1-2 °C / min;

3. temperature control accuracy: within ± 2 °C, the use of low temperature tank temperature -35 °C, high temperature tank temperature 140 °C.

4. medium groove tank material: 304 stainless steel plate welding, wall thickness: 1.5mm; low temperature medium tank insulation material: rubber fire insulation cotton; high temperature medium tank insulation material: asbestos insulation board;

5. the largest specimen limit: specimen: aluminum specimen; total mass of the specimen: 10Kg, the largest internal volume 10L;

6. There must be a balance tube between the two tanks, high and low liquid level alarm, liquid level sensor, liquid inlet, liquid level gauge, temperature sensor and temperature ultra-high temperature alarm;

7. The high and low temperature tank cover needs to be controlled by a cylinder, and the control valve is controlled by an O-valve.


2, temperature control system

1. The low-temperature tank circulation compressor is a semi-hermetic screw compressor, which adopts the German brand Bitzer, and the pre-cooling compressor for pipeline circulation is a fully-closed scroll compressor, which adopts the American brand Copeland.

2. The temperature control accuracy of the unit is ±2°C and the temperature uniformity in the media box is ≤2°C.

3. The cooling system is designed with multiple protection functions. The unit's control panel can determine the location of the fault.

4. The protection functions of the cold and hot integrated unit include high and low pressure protection; safety valve; overheat protection; overload protection; reverse phase; phase loss; water flow protection, etc.


3, the media circulation system

1. High-low temperature medium tank is equal volume 240L, effective volume is 200L, welding process is full-finished welding, supporting liquid level observation window, lowest liquid discharge port, artificial fluid inlet, overflow port, tight insulation, beautiful appearance, Durable and meet user requirements.

2. The medium line valve is made of 304 stainless steel. The flange connection is convenient for maintenance.

3. with its own circulatory system to ensure the temperature accuracy range of the medium;
