OVERVIEW Hitachi's commercial/industrial dehumidifiers are valuable in various fields for the purpose of dehumidification and drying. Places where humidity tends to be high due to the presence of water and steam - Indoor pools and fitness clubs - Dehumidification and drying of bathing areas in public bathrooms and inns Dehumidification, drying, and storing : 04 At food processing plants, manufacturing facilities and logistics businesses - Drying and storing of fresh and processed food - Drying of food processing plants after cleaning with water At workshops and work facilities -...

MAIN – FEATURES ENHANCED CONTROL FEATURES Small floor type (inverter-equipped) < Reheating only type > The optional multi-function wired controller supports various functions. * For the following functions, an optional multi-function wired controller is required. * If the optional caster wagon is used, mount the controller on the side of the wagon. Small floor type with small footprint. Enhanced control features by optional multi-function wired controller. Multiple unit control function Extensive product line-up Up to 10 dehumidifiers (small floor type) can be controlled at the same time....

MAIN – FEATURES REDUCED ENERGY CONSUMPTION (inverter-equipped) < Reheating only type > Inverter control allows the unit to be used under a wide range of dehumidification load conditions as well as reducing energy consumption. It also makes it possible to reach the set humidity level within a shorter time and to respond to a greater fluctuation of dehumidification load. Depending on the fluctuation of the dehumidification load, the compressor speed is controlled by the inverter to adjust the dehumidification capacity. Compared to the constant speed type, power consumption is reduced as the...

MAIN – FEATURES Cooling Operation Floor type (inverter-equipped) < Reheating and cooling type > Model Inverter Inverter control allows the unit to be used under a wide range of dehumidification load conditions as well as reducing energy consumption. As it is a reheating and cooling type, it can prevent temperature increases in the room. Floor type (constant speed) Floor type (constant speed) Model Inverter (Outdoor unit) (Outdoor unit) *1. Plenum chamber is optional. Extensive product line-up Model Equivalent horsepower Cooling capacity Depending on the fluctuation of the dehumidification...

COMMON – FEATURES Floor type Floor type (inverter-equipped) & Small floor type (inverter-equipped) (inverter-equipped) WIDE SELECTION OF OPTIONAL PARTS A wide selection of optional parts is supported, such as a filter box for the front suction, duct set for the rear suction, and high efficiency filter. (For details, refer to P38~P45.) The system performs demand control by detecting the operating current of the compressor. This feature helps suppress the maximum power by cutting the power consumption which exceeds the set power range. * Small floor type require the optional multi-function...

COMMON – FEATURES Useful power saving features Floor type (inverter-equipped) & Small floor type (inverter-equipped) * The following three control functions cannot be enabled simultaneously. It takes a long time to reach the set humidity/temperature (reheating andcooling type). MULTI-FUNCTION OF CONTROL PANEL DEHUMIDIFICATION CAPACITY CONTROL The control panel supports the wired controller (PC-RKF). You can configure various features by simple operation. Two power-saving modes are available. * The small floor type requires the optional multi-function wired controller. Peak save mode...

COMMON – FEATURES STANDARD ANTICORROSIVE COATING (INDOOR UNIT) Floor type (inverter-equipped) & Small floor type (inverter-equipped) MULTIPLE UNIT CONTROL Up to 10 dehumidifiers can be controlled at the same time from a single control panel. Following the wiring guideline below, wire the units correctly. Wiring guideӏine Remove the wiring connecting the control panels of units #1 through #9 and the terminal block (TB2). (Example for floor type) Heat exchanger (anticorrosive coating) (Example for small floor type) *Clear acrylic resin coating Generally, the hairpin tubes on the ends of the...

Drain Piping Connection (R1/2)(Both Side) Expanded Metal Dehumidification capacity characteristic curve Indoor Air Inlet Humidity (%) Note: 1. The diagram shows the values when a dehumidifier inverter with the above capacity runs at maximum frequency.The "○" in the diagram indicates the maximum capacity for standard operating conditions: Air inlet temperature 25°C, indoor air inlet humidity 80%. 2. The "●" in the diagram indicates the capacity at the nominal operation under standard operating conditions. 3. When the air inlet temperature falls below approximately 20°C, defrosting starts and...
