Product catalog summary
Overview
Hitachi's industrial dehumidifiers are engineered for diverse applications such as food drying, precision machinery room dehumidification, and concrete drying. They employ a refrigeration cycle to cool and condense humid air, effectively removing moisture. Models are available in reheating and cooling types to maintain stable room temperatures.
Product Line-Up
The product range includes compact floor models with advanced control features via an optional multi-function wired controller, enabling multiple unit control, remote operation, and easy timer settings.
Main Features
Models like RK-NP08PVX and RK-NP2LVX boast high dehumidification capacity and energy efficiency through inverter control, allowing optimal performance under varying load conditions. A powerful mode is available for rapid response to increased dehumidification demands.
Specifications & Dimensions
Specifications include dehumidification capacity, compressor output, and energy consumption. Inverter models offer up to 20% annual power consumption savings compared to constant speed types.
Optional Parts and Modifications
A variety of optional parts such as filter boxes, duct sets, and high-efficiency filters are available. Installation is streamlined with pre-assembled components like the plenum chamber.
Common Features
Inverter-equipped models feature easier installation and improved serviceability, with direct blower-motor connections eliminating V belt adjustments. The design supports easy cleaning and maintenance, minimizing performance deterioration risks.
Demand Control and Power Management
The demand control feature manages compressor operating current to limit maximum power consumption, with settings from 100% to 40% of rated power. A wave mode alternates demand control to reduce humidity fluctuations and power use. Setup requires distributor assistance.
Operating Temperature Range
The dehumidifiers function across a wide temperature range, adaptable to various humidity and temperature conditions.
Control Panel Features
The control panel includes a multi-function wired controller, powerful dehumidification mode, full-dot LCD, and easy timer function. It displays power consumption for effective power-saving management.
Power Saving Modes
Peak Save and Restrict Mode adjust dehumidification capacity and compressor speed to manage power consumption within desired limits.
Intermittent Operation Control
This feature cycles between dehumidification and thermo-off modes to conserve power, with specific settings for reheat mode.
Multiple Unit Control
Up to 10 dehumidifiers can be controlled from a single panel, with specific wiring guidelines. Different types or series cannot be combined for control.
Anticorrosive Coating
Standard anticorrosive coating is applied to indoor units, particularly on evaporator hairpin tubes, to prevent corrosion.
Antibacterial and Deodorant Air Filters
Antibacterial filters have activity values of 5.3 to 5.4, tested per JIS standards. Deodorant filters are effective against certain odors but not toxic substances like carbon monoxide.
Installation and Usage Notes
Remote control operations require a twisted-pair cable of 0.75mm2 or greater. The duct chamber includes a flexible duct but is not self-supporting.
Optional Parts and Models
Models like RK-NP2LVX, RK-NP4LVX, and RK-NP8LVX have specific parts like plenum chambers and filter boxes. Detailed specifications for filters include dimensions and maintenance periods.
Filter Specifications
Long life filters have a 50% dust collection efficiency, while high efficiency filters achieve 65% using the colorimetric method. Deodorant filters absorb general odors and are available for rear suction configurations.
Maintenance and Cleaning
Filters can be reused by drying in sunlight or washing with water, but detergents should be avoided. Maintenance periods depend on usage conditions, and filter installation affects air volume and dehumidification capacity.

MAIN - EATURES Floor type (inverter-equipped) < Reheating only type > REDUCED ENERGY CONSUMPTION HITACHI 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...
