Heatless

Heatless Desiccant Dryers

PH heatless adsorption dryers use dry, expanded purge air to remove moisture from the desiccant material. Incorporating high-quality components, PH heatless desiccant dryers provide you with clean, dry air to extend the life of your equipment and products. Heatless desiccant dryers use the compressed air to remove any moisture from the desiccant material.

PH 2-45 HE

Incorporating high-quality components, PH heatless adsorption dryers provide you with clean, dry air to extend the life of your equipment and products. Heatless adsorption dryers use dry, expanded purge air to remove moisture from the desiccant material.

PH 2-45 HE adsorption dryers are capable of drying air to a PDP of -70°C/-94° F, simply by reducing the flow, thanks to the use of carefully selected molecular sieves. The desiccant is housed in a robust extruded aluminum body, which can operate until 16 barg/232 psig (fatigue load). The dryers are equipped with a mounted pre-filter and an integrated after-filter as standard, can be installed vertically and can also be wall-mounted with a specially designed wall-mounting kit (optional).

The controller ensures the lowest operational costs thanks to compressor synchronization and the optional PDP control. LED’s on the controller indicate whether power supply is connected, towers are pressurized and solenoids are functioning properly. It also provides with preventive maintenance information. Alarms can also be triggered remote thanks to the available voltage-free contact.

PH 55-550 HE

PH 55-550 HE adsorption dryers are available in 3 PDP variants:
-20°C/-4°F , -40C0/-40°F and -70°C/-94°F, each optimized to provide the lowest purge loss. The unique manifold (patent pending) includes pilot air controlled 3/2-way valves, which switch fast and reliably. The pressure drop over the valves is reduced to a minimum. This does not only result in a low pressure drop over the dryer, but also ensures maximum purge air expansion during regeneration. The latter makes that the purge consumption of the dryers has been reduced significantly.

The desiccant is spring-loaded and housed in a robust extruded aluminum body, which can operate up to 14 barg/203 psig (fatigue load). The dryers are equipped with a mounted pre-filter and after-filter as standard and can also be wall-mounted with a specially designed wall-mounting kit (optional).

The controller indicates whether power supply is connected, towers are pressurized, valves are functioning properly or preventive maintenance needs to be done. In case the optional PDP control is connected, the PDP value can monitored from the display. Alarms and warnings can also be triggered remote with the available voltage-free contacts.

Optionally the Purelogic™ can be used as central brain of the adsorption dryer.

The PurelogicTM offers impressive control and monitoring capabilities, and can communicate with industrial protocols as Modbus, Profibus or Ethernet/IP.

Benefits:

Advanced energy management for lowest operating costs
– Compressor synchronization
– Purge nozzle optimization
– PDP control (optional)
Best-in-class performance thanks to (patent pending)
– Lowest pressure drop during drying
– Lowest purge loss by ensuring maximum purge air expansion during regeneration
Low noise levels during purge and blow-off

– PDP -70°C/-94°F: molecular sieves
Spring-loaded desiccant, minimizing the risk of crushing
Counter-current regeneration for optimal energy efficiency and guaranteed dry air
Designed for transportability & mountability
– Wall-mounting kit for PH 55-190 HE (optional)
Optimal control and monitoring thanks to the Purelogic™ controller (optional)
Desiccant bags for easy service from the top

PH 55-550 S

PH 55-550 S adsorption dryers are available in 2 PDP variants:
-20°C/-4°F and -40C0/-40°F.The unique manifold (patent pending) includes pilot air controlled 3/2-way valves, which switch fast and reliably.

The desiccant is spring-loaded and housed in a robust extruded aluminum body, which can operate up to 14 barg/203 psig (fatigue load). Pre- and afterfilters are delivered as standard with every dryer.

Operating costs are optimized at all times thanks to the availability of compressor synchronization and purge nozzle optimization as standard and PDP control as option. The full machine status can be checked on the display of the controller and the vessel pressure gauges on the unit. The controller indicates whether power supply is connected, towers are pressurized, valves are functioning properly or preventive maintenance needs to be done. In case the optional PDP control is connected, the PDP value can monitored from the display. Alarms and warnings can also be triggered remote with the available voltage-free contacts.
