Working Principle 2. Application HYDAC Brazed Plate Heat Exchanger (BPHE) consists of chevron plates of acid-resistant stainless steel. Every other plate is reversed so the ridges of the herringbone pattern intersect one another on adjacent plates forming a lattice on contact points. When these points are vacuum brazed together, two separate systems of channels for two media flow in counter-current are formed. The lattice structure causes vigorous turbulence, thus, ensuring maximum heat transfer, HYDAC BPHE can be used for various medias: - All type of refrigerants; ammonia will be used for nickel brazed. - Organic solvents - Water - Oil - Various brine solutions (glycol mixtures, CaCl2, alcohols etc) The BPHE is a highly efficient, corrosion-resistant and pressure resistant heat exchanger. The standard BPHE is designed to meet 30 bar, 200°C, and the largest-size handles a maximum flow capacity of 900 liter/min. HYDAC BPHE can be used: - Heat pumps - Industrial chiller; plastic machines, welding machines, hydraulic presses (oil), and compressor oil cooling Air conditioning - Refrigeration - Air dryer - Water cooler; drinking water or process water for various industries - Temperature holding for storage tanks - Heat recovery including heat recycling from hot steam - Indoor heating including floor heating Refrigerant applications, BPHE function as: - Evaporators - Condensers Super-heaters for gas Desuper-heaters for gas Subcoolers for condensate - Economizers - Intercoolers - Oil coolers 6.

Anti-Freezing Protection Methods for BPHE! *Always install your BPHE vertically, especially for a refrigerant system, in order to be secured and keep less volume of water below the connector. * In order to achieve high thermal efficiency and high heat transfer rates, BPHE is better to be installed in counter flow direction. When BPHE works as an Evaporator, the two-phased (liquid an gas) refrigerant enters the evaporator at the bottom left connector and the single-phased (gas) refrigerant leaves the evaporator from the top left connector after heat transferring. The water enters at the top right connector and leaves from the bottom right. In the case of evaporator, heat is transferred from water to refrigerant and both fluids are in counter flow direction, *When BPHE works as a condenser, the single-phased (gas) refrigerant enters the condenser at top left connector and the single-phased (liquid) refrigerant leaves the condenser from the bottom left connector The water enters the condenser at bottom right and leaves the condenser from top right. In the case of condenser, heat is transferred from refrigerant to water and both fluids are in counter flow direction. -Any formation of freezing oricing will damage BPHE and the refrigeration system. The following methods will prevent BPHE from freezing up -Use brine (e.g. glycol) when evaporation temperature is close to the freezing point. -Low working pressure will cause low evaporation temperature. Ir the evaporation temperature is below 00, it will cause the water to freeze up. As a result, evaporator is being expanded and finally cracked open especially the bottom portion of the PHE. Since bottom portion has the lowest temperature. -To start the refrigeration system, always starting with the water pump for a few minutes, and then starting the compressor. To stop the system, always stopping with the compressor, and then stopping the water pump. (1) Low Pressure Cut-off Switch (LP) A low-pressure cut-off switch shall be installed and the value shall be set properly. When the actual evaporation pressure is lower than the setting value, the compressor will be cut off automatically. (2) Low Temperature Thermostat (LT) The function of thermostat is to prevent evaporation temperature going under 0°C. If evaporation temperature is always above 0C; than water has no chance to freeze up and expand. (3) Water Temperature Sensor Installation of an Anti-freezing temperature sensor near the water outlet is another method to prevent the water from freezing up. The setting temperature is suggested at 4°C for buffering purpose. (4) Water Flow Switch Installation of a water flow switch in the water circuit can prevent possible BPHE freeze-up due to low water flow rate, Usually, low water flow rate may cause by malfunction of water pump, leaking pipes, pipe blockage due to pipe contamination or dirty filter. *Mounting suggestions: There are four different ways to mount the BPHE: (a)Bottom support (b) Sheet metal bracket, (c) Crossbar& bolts, (d) Stud bolts (a) (b) (C) (d) -All items should be supported independently. -Do not apply excessive forces to the fittings. -Except for small in sized HYDAC HEX $400, brazed PHE cannot fasten directly to the fittings/piping. -Using flexible hoses or vibration dampers to reduce pulsation, shock or vibrations those are caused by the operating system. 12. Warranty Terms 13. Label and Marking Free of charge if what defects are caused by manufacturing material or manufacturing workmanship. - Warranty period is 12 months after exit factory delivery or else, by contract with the purchaser. A1 TOP B2 HYDAC brazed plate heat exchanger Type: - Exceptions are: (1) The failure or malfunction of BPHE is caused by improper or negligent usage of BPHE.

A1B21 OTO CE A2 HYDAC B1 Manufactured by KHT Taiwan For tracking purposes, model name and serial number will be embossed on the plate of the front cover below the two upper connectors of the BPHE. 9. Soldering Instruction 11. Warning Cleaning and degreasing the surface of copper pipes and PHE connectors before soldering is important. To avoid the inside of copper pipes and BPHE from Oxidation, protect the inside with N,-gas. Put the BPHE on a flat surface and wrap a wet rag around the connectors to protect the BPHE from excessive heatino. Use a 40-45% silver alloy soldering rod to weld the copper pipe into the connector at a max. of 800°C. After soldering, clean and dry the connection and BPHE. 10. Cleaning Cleaning of fouled plate heat exchangers is important Back flushing will remove most of the soft debris that is blocked the inside. The solution used by back flushing shall be weak acid with concentration less than 5%, for example citric acid. If acidity is too high, the copper and stainless steel, which is Inside the PHE, might be etched or corroded. Before restarting the system, flush the plate heat exchanger with large amounts of fresh water to purge any remaining acid solution. - Fluid that is explosive, extremely flammable, highly toxicant, highly corrosive, hazardous or etc. Cannot apply to BPHE. Examples are ammonia, nitric acid. sulfuric acid, etc. When unknown quality of water is applied to BPHE. filter and strainer should be place at the water inlet of BPHE to filter out the dirt or large particles, Mesh size of around 20 is suitable for most cases. Blockage of evaporator due to dirt or large particles will reduce the flow rate of water then the water will freeze up, consequently might cause the crack of the BPHE. Chlorinated water. seawater, etc. are not suitable for BPHE because it will corrode and damage the BPHE. For example, swimming pool water - Solution which applied to BPHE shall have PH value range between 6 - 8. Ground water with high sulfuric compound, sulfuric acid, low PH value, may cause gradual copper corrosion and damage the BPHE in a few years, Rubber ring always mounts or adheres the bottom edge of the BPHE in order to protect the hand and wrist against the sharp metal edges. If the rubber ring is not a required part of your order, watch out for the sharp metal edge. - When moving BPHE, always wear gloves and pay attention to the sharp edges around the bottom of BPHE. Some BPHE comes with rubber strips that covers the sharp edge of the BPHE but some does not. It all depends on your request.
