HUIDA HD-3003 Humidity Chamber 0~150 ℃/150L

Features

1. HD-3001 adopts a balanced temperature control system to control the SSR drive in PID mode, so that the heating amount of the system is equal to the heat loss, so it can be used stably for a long time.

2. Operating environment (when the machine is empty, the room temperature of the air-cooled machine is at room temperature 25°C, or the water temperature of the water-cooled type is at 25°C)

Cabinet material

1. Enclosure Material: brushed stainless steel plate welded or sprayed.

2. Inner box material: (SUS#304) black-faced stainless steel plate welded all around.

3. Observation window: one observation window of rectangular multi-layer hollow heat-insulating glass (150×150mm) with lighting installed on the observation window.

4. Insulation material: Polyurethane foam high temperature and high pressure foaming agent connects the inner box and the outer box into a whole.

5. Load capacity of the sample rack: not more than 30 kg.

6. Cable hole: one cable hole Φ30mm is opened on the back of the box.

7. The bottom adopts PU movable wheels that can be fixed and adjusted horizontally.

refrigeration system

1. Compressor: fully enclosed, effective and economical refrigeration compressor.

2. Refrigerant: Use DuPont's environmental protection refrigerant R404A high temperature cycle and R23A low temperature cycle (refrigeration cycle).

3. Welding: The pipelines of the whole system are tested for leak detection with nitrogen and pressure for 24 hours.

4. Performance: The heating and cooling systems are completely independent.

5. Heat exchanger: inner spiral K-TYPE refrigerant copper tube.

6. Condenser: wavy fin type forced water-cooled condenser.

7. Evaporator: slope type FIN-TUBE evaporator.

8. Expansion system: All the action programs of the refrigeration system are completely controlled by the microcomputer controller, which can achieve the advantages of efficiency and power saving. The refrigeration system has a throttling device to control the flow of refrigerant, which is energy-saving and low-noise.

9. Performance: The low temperature system adopts a unitary refrigeration system loop, and the cooling rate is fast.

air conditioning system

1. Air conditioning method: forced ventilation internal balance temperature regulation method (BTC). This method means that in the case of continuous operation of the refrigeration system, the control system controls the output of the heater according to the set temperature point through the PID automatic calculation output, and finally achieves a dynamic balance.

2. Air circulation device: Built-in air-conditioning room, circulating air duct and long-axis centrifugal fan, using effective refrigerator and energy regulation system, and effective exchange through effective fans to achieve the purpose of temperature change. By improving the air flow of the air, the air flow rate and the heat exchange capacity with the heater and the air surface cooler are improved, thereby greatly improving the temperature uniformity of the Test Chamber.

3. Air cooling method: multi-stage diaphragm air heat exchanger.

heating control system

1. U-shaped fin-type high-speed heating electric heater is adopted.

2. Completely independent system, does not affect the refrigeration and control circuit.

3. The output power of temperature control is automatically calculated by microcomputer PID to achieve high precision and effective power consumption.

4. The heating rate is calculated according to the heat content load of the test object.

humidification system

1. Adopt the micro-motion humidification system of electronic parallel mode.

2. The humidifying barrel is made of stainless steel and has a water level observation window.

3. With overheating and overflow double guarantee device.

4. The humidification and dehumidification systems are completely independent.

5. Water level control adopts mechanical floating ball water raft to prevent electronic misoperation.

6. The wet water supply adopts an automatic water replenishment system with a filter, and the buyer does not need to manually add water.

7. Adopt non-recycling waterway system.

dehumidification system

1. Independent refrigeration compression system dehumidification method.

2. Dew point temperature (ADP) laminar flow contact dehumidification method of evaporator vessel tube.

12: Safety protection measures:

1. Two groups of solid-state relay (SSR) (one group for temperature and one group for humidity);

2. One set of over-temperature protection switch;

3. Two sets of water shortage protection switches;

4. The refrigeration system compressor is equipped with over-temperature and overload protection devices;

5. Compressor overcurrent protection switch;

6. One Japanese-made phase loss protection switch (if the power supply is single-phase, there is no such accessory);

7. Two fast power fuses;

8. No fuse switch;

9. Line fuse and full sheath terminal;
