DS+Series energy-saving refrigeration dryer


》Working principle

The refrigerated compressed air dryer (referred to as the cold dryer) is based on the principle of freezing and dehumidification, which forcedly cools the compressed air below the required dew point temperature, so as to condense the large amount of water vapor and oil mist contained in it into liquid droplets. It is a kind of purification equipment that separates and drains the compressed air out of the machine by draining the compressed air.

The DS series dryer is a reliable and low-energy air handling solution. In order to prevent the precipitation of condensed water in the compressed air, and the resulting corrosion and equipment damage, we must dry the compressed air. This is also the reason why the DS series dryer can remove water from the compressed air and therefore remove it. The big hazard of the air piping system.

Adding filtering equipment to the compression system will further improve the air quality, while reducing the possibility of damage to pneumatic tools and equipment, and improving the quality of the final product.

DAH/DAHV series heating regeneration / blast heating regeneration adsorption dryer


》Working principle

DAH series heating regeneration adsorption dryer uses a small amount of dry product air for heating, blowing and cooling regeneration, with an average air consumption rate of 6-8%. Compared with non-heat regeneration dryers, the air consumption is only half of that. The process is simple and easy to operate. The maintenance is convenient, and the product has a good comprehensive cost performance.

DAHV series blast heating regeneration adsorption dryer adopts the process of ambient air blast regeneration, so it can save a lot of product gas required for traditional process regeneration. The process steps of blast regeneration include heating and blowing cooling. When heating, the regeneration gas source comes from the ambient air boosted by the blower, and it is heated to the regeneration temperature by an external heater as the regeneration gas desorbed by the adsorber bed. During the regeneration operation, the regeneration heating gas heats and analyzes the adsorbent bed, and the separated water vapor is carried by the regeneration gas and taken out of the adsorber. Regeneration blowing or taking from its own dry air, after decompression, as regeneration blowing gas, or air circulation cooling separation as regeneration blowing gas, blowing and cooling the bed to meet the needs of the next stage of adsorption work, avoiding air The outlet dew point is unstable due to the presence of bed temperature.

AD series zero consumption drain


》Working principle

When the condensate enters the drain tank, the water level continues to rise. When the water level reaches the high water level, it is sensed by the liquid level sensor, and the drain valve is controlled to open, so that the condensate can be quickly discharged.

When the drain valve continues to converge to the condensate water level, the liquid level sensor controls the drain valve to close quickly. At this time, the liquid level is still some distance away from the drain valve outlet, so there will be no compressed air leakage during the draining process.

Once the drain valve is dirty or jammed and the condensate level is too high or too low, the liquid level sensor will automatically sense, and the control circuit will automatically switch to the self-cleaning drainage program. At this time, the yellow indicator light on the panel flashes and the remote abnormal signal is displayed. When it is turned on, the drain solenoid valve is opened for 5 seconds every 3 minutes to make the drain valve in an alternate loading/sanction state to facilitate the discharge of foreign matter, etc., until the drain water level returns to normal.
