Note:
■ The nominal cooling capacity (1) is measured under the following
conditions: The indoor dry/wet bulb reads 27/19 °C and the outdoor
dry/ wet bulb reads 35/24 °C. The nominal heating capacity (1)
is measured under the following conditions: The indoor dry bulb
reads 20 °C and the outdoor dry/wet bulb reads 7/6 °C.
■ The nominal cooling capacity (2) is measured under the following conditions: The indoor dry/wet bulb reads 24/17 °C and the outdoor dry/wet bulb reads 35/24 °C. The nominal heating capacity (2) is measured under the following conditions: The indoor dry bulb reads 24 °C and the outdoor dry/wet bulb reads 7/6 °C.
■ The nominal cooling capacity does not consider heat losses of the fan motor of the indoor unit. The external static pressure can be customized, in which case the power of the air supply motor changes accordingly.
■ The specifications are subject to change due to product improvements without prior notice.
■ The fresh air flow of the unit cannot be larger than 20%.
Consolidated Structure
The unit features a compact structure, easy assembly, and solid seal. It adopts special seal glue handling, providing air leakage rate as low as 0.3%. The 30mm (standard)/50mm (optional) enhanced high-pressure non-fluorine polyurethane double-layer foamed panel delivers a solid insulation performance and high bearing capacity, meeting requirements of a purifying unit for high residual pressure.
High Efficient and Low Noise
The outdoor unit adopts brand-name fully hermetic volute compressors that deliver high efficiency, low noise, and strong resistance to hydraulic shock and run at temperature ranging from -10°C to 48°C, meeting cleaning requirements in various regions and scenarios.
The indoor unit adopts imported high-quality centrifugal fans with double air intakes (model selection of the fans has passed AMCA certification) or unhoused fans (optional), and is equipped with dedicated anti-vibration measures for quiet running.
Load Matching
The evaporation section of the indoor unit can be equipped with a bypass valve. The direct evaporation coil supports combination with multiple cooling capacity options according to different conditions for a wide range of fresh air/air return scenarios. The outdoor unit of a large-capacity cooling unit adopts modular design, allowing differential energy regulation during use, lowering the operating cost, and reducing shock on the grid at startup.
Sterilization
The indoor unit adopts a dry water drainage tray that has
no residual condensed water and prevents bacteria. A
stainless steel water tray is optional. In addition, a
sterilization device such as efficient UV sterilization lamp
and ozone generator can be configured as required to eliminate
bacteria and effectively
suppress microbes in the system.
Saving Investment
The unit has a built-in cooling and heating source and does not require a chilled or cooling water system, greatly saving user investment, and making the unit structure simple and compact. No dedicated equipment room is required. The unit can run immediately after cabling and piping. The installation, use, and maintenance are easy.
Smart Control
The unit adopts integrated digital electromechanical design and is equipped with a smart controller, providing multiple control functions such as constant temperature, constant humidity, function setting, fault alarm, and remote monitoring to ensure safe and reliable unit running.
Prevention of Cold Bridge
The unit adopts inner skeleton design and high-strength
foam seals and tight repair door structure, effectively
preventing cold bridge between wall plates, between wall plate
and inner skeleton,
or at the repair door. The panel of the unit is wrapped with
solid insulating UPVC plastic at all sides, avoiding
direct contact with thermal conductive parts, providing T1
class insulation performance, eliminating cold bridge, and
preventing cooling loss.
High-Quality Filters
The unit adopts a high-quality multi-level (primary, medium, sub-high, and high efficiency) air filtering system. The filtering class meets the requirements of a special clean room, and can effectively suppress organic compounds on the filtering paper.
Purification Design
A special frame structure ensures smooth surface in the unit. The inner stainless steel surface and an efficient heat exchanger (optional) made of hydrophilic aluminum foil can effectively prevent dust accumulation and re-entrainment. The special design and materials can resist disinfectant and air erosion and are favorable for regular cleaning and sterilization.
Multi-System Design
The outdoor unit adopts modular design and starts level by level, efficiently reducing shock on the grid. Multiple levels of cooling are provided, allowing differential energy regulation under different load conditions and reducing the operating cost. The compressors wear in a balanced manner, prolonging the lifecycle.
