| The BKP™ Series (Commercial/Industrial Packaged Dehumidifiers) |
Standard features
Design Features The design basis of the BKP™ Series lies in the Dinh Dehumidifier Heat Pipe principle. By incorporating a patented process of passively precooling and reheating air, the BKP™ is able to provide greater performance and is more energy efficient. The result is a dehumidification system with the ability to remove 40% to 50% more moisture than other systems while using the same amount of energy.  Narrow Band Settings -- The dehumidistat allows narrow band settings for specific relative humidity requirements.
Quality Cabinet -- Heavy duty power coated galvanized steel cabinet.
Benefits
|
Each BKP™ Series dehumidifier unit is factory assembled, inspected and tested to ensure maximum performance. The standard BKP™ Series unit shall include the following:
Indoor unit and outdoor remote condenser casing shall be constructed of 20 gauge galvanized (Bonderite) steel sheet. All panels outside shall be cleaned, coated with Epoxy primer and painted with acrylic paint. The indoor unit cabinet interior shall be lined with 1" fiberglass duct liner for thermal and acoustical insulation.
The compressor shall be heavy duty Copelandâ Scroll, Matsushita Rotary or equivalent hermetic type with permanent split capacitor (PSC) motor internally protected from over-heating. The compressor shall be equipped with an internal suspension system and external rubber vibration absorbers.
Evaporator and condenser coils shall be constructed of seamless copper tubing with internal microgrooves for highest heat transfer efficiency. The tubes shall be expanded into the collars of aluminum fins to ensure tight metal to metal contact. The coils shall be circuited so the refrigerant moves counter flow to the entering air. Copper to copper brazing shall be made with a suitable flux and silver brazing alloy. After brazing, each coil shall be pressure tested to 400 psig (2.86 MPa). The suction line shall be insulated to prevent condensation from forming and dripping into the machine. A constant pressure expansion valve shall be installed and factory calibrated to operate efficiently at low head pressure reducing the power consumption at low ambient. Units shall have an installed heat exchanger suction accumulator to ensure liquid free refrigerant at the compressor. Each BKP™ unit shall be precisely charged (except units with remote condenser) with refrigerant and tested for proper performance before shipping.
HPT’s patented dehumidifier heat pipes shall be installed wrapping around the evaporator coil for the purpose of precooling the incoming air and reheating the supply air. This results in increased moisture removal by the evaporator and a lower relative humidity of the supply air. HPT’s dehumidifier heat pipes are passive, but ultra-fast heat transfer devices and are constructed with microgrooved copper tubes and aluminum fins. They shall be evacuated and charged with the appropriate amount of working fluid, then sealed and tested for proper operation and performance.
Centrifugal blowers for the indoor unit shall be of the forward curved type, statically and dynamically balanced for efficient operation. The fan motor shall be high efficiency direct drive of the permanent split capacitor (PSC) type with sleeve bearings.
Drain pan shall be constructed of 20 gauge galvanized steel coated with a drip pan coating and have a 3/4" female NPT connection.
Indoor units (except BKP™ 100 and 175) shall have outlet 1" duct flanges. A standard filter rack is installed on the return air side of cabinet for a disposable type fiberglass air filter. The BKP™ 100 and 175 shall be manufactured with return and supply air grilles. The grilles shall be made of aluminum with a white enamel finish. A disposable fiberglass filter shall be installed inside the return air grille.
Electrical control parts shall be located in an accessible enclosure pre-wired and tested for operation. Enclosure shall contain compressor contactor, lockout relay, start capacitor (except CopelandÒ scroll compressors), high and low pressure switch, time delay and low voltage transformer to supply 24 volt control power. The lockout system will shut the unit down if the system pressures exceed limits of safety switches, or on failure of the condensate drain system.
A dehumidistat shall be installed on the unit (BKP™ 100 and 175 only) or supplied with other models to be remotely mounted. The dehumidistat has an adjustable range of 10-90% RH and can be locked on a setting. A reset light and button on the dehumidistat for indication of a lockout condition and provide for resetting.
A provided thermostat to be installed inside the room to control the BKP™ operation for cooling or maximum dehumidification. The thermostat shall be of the mercury switch type with sealed contacts for protection against dirt and moisture and have an adjustable range from 55°F to 90°F. |
| The BKP™ Series |
Models 100 to 1250 The BKP™ Series (100, 175, 250, 450, 750, 1000, and 1250) are the most sophisticated and efficient dehumidification systems available on the market. The units are based on a patented heat pipe technology of HPT and designed for a wide variety of commercial and industrial applications. Due to their integrated heat pipes, the BKPs use about half the energy when compared to conventional dehumidifiers of same capacity currently on the market. Quiet blowers and compressors make the BKP™ Series ideal for working environments. The BKPs are precisely controlled by a dehumidistat of HPT design to maintain a constant relative humidity, the BKPs operate independently from the central air conditioning system. Various models with water removal capacity from 100 up to 1250 pints per day. The BKP™ units can operate in a wide range of environment conditions from 55°F/100% RH to 95°F/50% RH inlet air. |

| The BKP-AC™ Series with Remote Condenser for Cooling |
Models 250-AC, 450-AC, 750-AC, 1000-AC, and 1250-AC The BKP-AC™ Models are equipped with remote outside condensers, making them "Total Air Conditioning Systems". They are capable of sensing the inside air conditions and will switch automatically to the appropriate mode of high dehumidification or dehumidification and cooling. While operating in the latter mode, the system heat goes to the remote condenser to be rejected to the outside environment. The BKP™ 350-AC, 450-AC, 750-AC and 1000-AC add 2.75, 3.5, 5 and 7.5 tons, respectively, to the cooling capacity of the existing central air conditioning system. The conventional method of using an oversized air conditioning system with reheat to dehumidify can be replaced by the BKP-AC™ dehumidifier to achieve the same purpose at a fraction of the operational cost. The BKP™ can also be used to treat fresh air to improve indoor air quality. In all, the BKP™ Series provide state-of-the-art dehumidification at lowest operating cost. They utilize proven components for maximum service and reliability. The unique design employs automatic temperature and pressure regulation of the refrigerant to provide the best performance over a wide range of conditions. The control system contains a safety shutdown which will activate on higher or lower than normal refrigerant pressure and can be easily reset at the dehumidistat. Other protection includes compressor overload and condensate back-up shut-down. |
