Safety
SPD series dehumidifier is in conformity with provisions of European security
requirements&standards, the safety works for people and equipment are done while
in design and manufacture process. In each section of the manual, there is safety
information, explicitly pointed out that the dangerous operation, "Danger Mark" was
marked in the front for warning
In the manual the best dehumidifier operation ways and procedures are provide d , but
they do guide only, are not liable for any personal responsibility or fulfill local safety
regulations. While installation and operation of the equipment, everyone shall bear
the liability:
• To p rotect equipment a ccording to the manual describes and explains the security ;
• Do care safety of yourself and others ;
• Dehumidification devices operation and maintenance works must be done by
related qualification professionals;
• Do not install dehumidification equipment around the explosion protection device s;
• Cut off power before open any cover in the housing;
• When the operation ende d , cooling equipment at least 15 minutes , then begin
maintenance ;
• If not for dehumidify equipment maintenance, the maintenance panel should be
closed if the maintenance is not being doing;
• Dehumidification equipment is limited to atmospheric pressure condition to
dehumidifying;
• F ilter device must be installed before using the dehumidification equipment ;
• Removing or deleting the marks/declares/notes in dehumidification equipment is
prohibited;
• The manual should be kept well for using in the future ;
• O riginal spare parts should be chosen;

Applications:
Applications:
It can be w idely used in hotels, office buildings, hospitals, commercial, research
institutions , swimming pools, and other places. Its working principle is evaporative
cooling, drying air under normal atmospheric pressure. Its working humidity range is
from 100%-30%(it can reduce the humidity down to 30% at most), and working
temp range is 5 ° C to 35 ° C , if it works beyond these ranges, it won ’ t dehumidify
enough, this problem is not belong to the quality of the equipment itself.

B: Airflow process: Utilizing refrigeration and internal air circulation to
cool the incoming air steam below its dew point, and the water vapor will be went
out through the plate below evaporator. T he processed air is reheated while passing
through the condens e r coil. T he heat removed by the evaporator is returned to the air
steam, resulting in an overall temperature increase to the processed air. So,
co n tinuous circulation, makes humidity gradually reduce.

Extra use energy-saving heat exchanger, i ntegrated using a liquid separator
reservoir and heat exchangers, it can effectively regulate the fluid flow volume ,
maximiz ing freezing capacity, and ensur ing compressor operat e well . Meanwhile,
dry filter was introduced in this s ystem to prevents clogging / impurities in expansion
v alve or capillary
★
Patented defrosting structure, it brings stable operation of refrigeration system
★
hydrophilic membrane fin(heat exchanger), heat transfer efficiency increases by
20%. Good insulation material also increases insulating effect by 15%

Compressor is the core part of this dehumidifier. I t d irect ly impact dehumidifier ’ s
performance. It is the heart of this dehumidifi er, provides powers for whole system.
We only use the international well-known brand c ompressors : Panasonic compressor
and Dakin compressor.

T hrottling device system is one of four important system in refrigeration systems.
It will reduce the liquid refrigerant(coming from condens e r) ’ s high pressure, make
the refrigerant absorb heat under low pressure(low temp) while vaporization .
Anyway, it is one important component to ensure high pressure in condenser and low
pressure in evaporator. As a result of direct expansion way, small cooling loss, high
efficiency, it also prevents fluid strik ing and over-heating. Expansion valve superheat
stable, the system is stable

★
Dehumidifier controller, desi gned by ourself according to this kind dehumidifier,
powerful, high overall operating performance. Motor overload and short circuit
protection is introduced too ;
Motivation switches are overload and short circuit protection.
★Starting-up delay protection: If the dehumidifier is cut off normally, it will take 3
minutes when turn it on again;
★
Shutdown delay protection: When the dehumidifier is cut off normally, fans will
keep running for 3 minutes, bring the needless heat out of dehumidifier.
★
Fans selection: Fan can stop/keep run n ing while the setting RH is reached,
customer have can set it according to their demands.
★High temperature protection: Prevent the compressor running continuously at high
temperatures;
★Low pressure protection: Prevents the dehumidifier run n ing without refrigerant;
avoids compressor burned.
