Description

In vacuum applications,a cold trap is a device that condenses all vapors(except the
permanent gases) into a liquid or solid. The main purpose is to prevent vapors being
produced by an experiment from entering the vacuum pump where they would condense
and contaminate it. Clod traps can also cool surfaces or baffles to prevent oil vapors flowing
from a pump into a chamber. In such a case,a baffle or section of pipe containing a number
of cooled vanes, will be attached to the inlet of an existing pumping system.

Features

Improve pump working efficiency:
1. The low temperature of the cold trap can condense the water vapor directly in the cold
trap, thus greatly improving the working efficiency of the vacuum pump.

Protect vacuum pump:
1. Pumps that use oil either as their working fluid (diffusion pumps), or as their lubricant (mechanical rotary pumps), are often the sources of contamination in vacuum systems.
Placing a cold trap at the mouth of such a pump greatly lowers the risk that oil vapors will
back stream into the cavity.

LCD PID controller:
1. P.I.D temperature controller provides accurate and reliable temperature control.
2. Large LCD display screen and interface provides for user-friendly operation.

Energy conservation and environmental protection:
1. Non-freon refrigeration improve cooling efficiency, lower noise, longer life time ensures the stability for long time running.

Safety:
Temperature deviation alarm.
Compressor over current, over heat, over load protection.

Design with
3 glass trap installation.
Upside opened a glass trap.
Easy internal observation with PC Transparent Cover.
Drain valve for easy discharge of collected liquid.
S304 internal bath can be used to do water or ethanol cooling experiments. If equipped
with glass condenser, it also can be used to deal with acid or organic solvents.

Option:
1. RS 485 connector and USB connector can connect computer to save the data.

2.2 Overview of structural functions

The cold trap is composed of a controller, a box, a refrigeration system, a glass condenser, and a circulation pump. The controller consists of a temperature controller, a temperature sensor, and the like. The box is made of high-quality thin steel plate, the surface is spray-coated, and the inner tank is made of stainless steel. The refrigeration system consists of a compressor, a condenser, an evaporation coil, and the like.

The equipment relies on the rapid cooling of the refrigeration system to reach the required temperature. The glass condenser series collection device is installed in the liquid tank and used in the vacuum system to complete the reliable operation of the vacuum system.

There is an inlet and outlet interface behind the cold trap. When the liquid outlet interface is not in use, the liquid can be discharged to keep the whole machine clean. The temperature controller is a double-row four-digit display digital controller composed of a CPU processor and peripheral circuits. Pt100 platinum resistance is used as the temperature sensing element, which has the advantages of high control precision and good stability, and alarm functions such as timing and over-temperature alarm protection.

Extended function - optional RS485/232 communication interface, through the connection of the computer, display and monitor the experimental data.

3. Use of the product

3.1 Preparation before use

1.1 The product should work normally under the following conditions of use.

a. Ambient temperature: 5°C~35°C; air relative humidity: ≤85%.

b. Atmospheric pressure: (86~106)KPa.

c. Altitude is not higher than 2000 meters.

d. Power supply: 220V/60HZ.

e. Keep away from heat sources, no corrosive gases around, no strong vibration sources and strong electromagnetic fields.

1.2 The base of the equipment to be placed needs to be flat and composed of non-combustible materials.

1.3 Keep at least 300mm of space around the equipment (front and back ventilation grille), well ventilated.

1.4 This equipment is equipped with a compressor. After the equipment is transported, do not operate immediately. After standing in the correct position, wait for (1~2) days to start working again to ensure that the compressor works normally.

1.5 When filling the bath, please be careful not to pour the liquid into the inside of the meter. It is recommended to open the heat cover to add water or other medium from the sink. The liquid must cover the evaporator.

1.6 Different baths should be added according to different temperature control ranges (super temperature is strictly prohibited).

3.4 Upper deviation alarm setting

The setting of the upper deviation is reasonable, can play the role of system temperature control or out of control protection, the product must be used when working.

Example: If the product is shipped with AL = 3.0, the alarm temperature is: (set temperature + AL value) °C.

3.5 Check the temperature control accuracy

3.5.1 With 0.1 °C index mercury thermometer (or resolution 0.1 °C digital thermometer) into the bath, the mercury end should be immersed in the bath and placed in the geometric center of the bath.

3.5.2 Choose a point within the range of product control, when the temperature measurement value is equal to the set value, then keep the temperature for about 1 hour. Observe that the difference between the actual measured value of the mercury thermometer and the measured value of the thermometer should be ≤ ± 0.5 °C.

3.6. Methods to improve temperature control accuracy

3.6.1When the product is used for a period of time, check the temperature control accuracy according to 5.2 method. If it exceeds ± 0.5 °C, it can be amended as follows:

3.6.2 Enter the parameter setting, find" " symbol,

After the formula is calculated, the value of PK is changed on the basis of the original factory (Note: a correction is not allowed, can be repeatedly modified until it meets).

4. Maintenance and precautions

1. The device must be connected to a well-grounded electrical outlet! To ensure personal safety.

2. When the bath is water, please pay attention to the use of temperature to prevent icing, resulting in inaccurate temperature control.

3. When replenishing the bath, the type of bath in the bath must be the same; (please note that the liquid medium in the working chamber must be filled with different bath according to different operating temperatures).

4. Use a flammable bath! Responsible for damage caused by improper use of the bath!

5. Connect the rubber hose, and press the clamp at the joint to prevent it from falling off.

6. Under continuous operation, the connection between the part of the bath cover and the circulation pump will become very cold. Therefore, when touching these places, be careful and prevent frostbite.

7. After filling the tank, carefully transport or tilt it at will, so as to avoid danger or equipment damage caused by immersion of cold liquid into the machine.

8. Must use clean water or medium to strictly prevent foreign matter such as sediment from entering the cooling system and damaging the circulating pump.

9. After use, turn off the power switch, unplug the power cord, insert the drain plug to drain (please pay attention to the bath temperature, be careful! To avoid frostbite) and dry the cabinet.
