Product description

? Adopts a high-efficiency heat exchanger which utilizes pre-cooling and re-heating systems

? Uses an eco-friendly refrigerant, R-134a.

? A panel is adopted which allows for temperature monitoring in each component (HYD-170 or later).

? Uses an IP54 Class (waterproof technique) axial fan

? A power drain is adopted which allows for a smooth and automatic discharge of condensate, which is generated in the heat exchanger.

HYD05 ­? HYD-35: auto drain (HAD-20) installed

HYD-50 or higher: power drain (HAD-100) installed

? Customized design suitable for all worksites

? For high pressure (where working pressure is 9.9 kg/cm or higher)

? Stainless heat exchanger

? Adding controllers; or ejecting contact points from the device

? Dryer for R-404A is an alternative refrigerant to R-22

? Various electrical specifications available

1. Control panel

A. HYD-150 or earlier model: a low pressure refrigerant gauge and an inlet air gauge are attached in order to display the operating condition of the system

B. HYD-300 or later model: a temperature indicator, which allows for temperature monitoring of each component, is attached in order to identify the condition of the system

C. A timer displays total operation time and thus provides convenience for maintenance; local/remote operation is available (HYD-170 to HYD-300)

2. Powder paint coating

A. Powder coating via static electricity that uses raw powder materials such as epoxy or polyethylene type powders; excellent corrosion resistance, and adhesive properties are better than solvent-based adhesives; durable enough to prevent corrosion

B. Durable against acids, alkali and impacts

C. Excellent waterproofing capability; rebuffs atmospheric pollution through vaporization of solvents; no risk of fire because of non-volatility

3. Drain

A. A drain is installed to discharge condensate that is produced in the heat exchanger, and a drain monitoring window allows for easy repair and/or maintenance

4. Heat exchanger

A. Adopts a high efficiency heat exchanger which utilizes pre-cooling and re-heating systems.

5. Fan motor

A. An IP54-class fan motor ensures waterproof and dustproof features of the product. An axial fan used therein enhances the efficiency of the condenser.

6. Pressure switch

A. High pressure switch: shuts the device down in order to protect the system when the refrigerant pressure exceeds the value set as a result of error(s) in the circulation system, when the coolant temperature rises, and/or when the ambient temperature rises.

B. Dual pressure switch: a combination switch for high pressure and low pressure; implements the functions of a high pressure switch, and shuts the device down in order to protect the system when the pressure of refrigerant collected by the refrigerant compressor falls below the pressure as set, due to leakages of refrigerant and so on.

7. Liquid separator/Accumulator

A. A device that improves performance and ensures the reliable operation of a refrigerated air dryer

B. Liquid separator: protects the compressor from spontaneous force that arises from the liquid refrigerant (liquid hammer phenomenon,NULL,NULL,NULL), which is collected in the compressor from the low pressure side of the evaporator.

C. Accumulator: stores liquid refrigerant that is discharged from the condenser in order to ensure satisfactory operation of the expansion valve

8. Refrigerant compressor

A. Our adoption of reciprocating refrigerators manufactured by well-known brands such as Tecumseh and Copeland guarantees reliable, first-rate performance.

9. Condenser

A. High quality and high efficiency condenser grooves are used to improve the efficiency of heat exchange.

B. Inner groove

i. The surface for heat transfer is improved by 40-70% compared to smooth tubes.

ii. Energy savings of 7-8%

iii. With respect to pressure inside of the tube, there is almost no loss compared to smooth tubes.

NOTE

1. R-404A alternative refrigerant to R-22 can be designed and manufactured upon request.

(Models earlier than HYD-20 use R-134A while later models use R-22 as their refrigerant.)

2. Different electrical specifications are available upon request.

(Models earlier than HYD-75 use a single phase while later models use a 3-phase.)

3. The processing flow rate is based on 60 Hz.

4. Models for high pressure are available upon request.

5. Models for larger specifications are also available.

6. The specifications listed above are subject to revision without notice for the purposes of quality improvement.
