Product catalog summary
Overview: The LHA Series Heat–Les™ Desiccant Air Dryer is designed to protect equipment from moisture in compressed air systems, achieving pressure dew points of ISO 8573.1 Class 1 and 2. It supports flow rates from 7 to 50 SCFM, suitable for environments with freezing temperatures.
Key Features:
  • Simple Heat–Les™ Design: Ensures consistent outlet pressure dew points with optimized desiccant beds and cycle times. Minimizes purge air usage and extends desiccant life.
  • Reliable Solid State Timer: Features a standard 4-minute cycle and ensures full repressurization before switching towers.
  • Integral Support Screens & Air Diffusers: Made of stainless steel for durability, preventing desiccant channeling.
  • Front Mounted Control Panel: Includes power and tower indicator lights, and an on-off switch.
  • Moisture Indicator Kit: Provides visual verification of dryer performance.
Product Specifications:
  • Dimensions and weight vary by model, with connections standardized at 1/2" NPT.
  • Models range from LHA-7 to LHA-50, with varying dimensions and weights.
Operation: Compressed air enters the dryer, is processed through two towers, and a portion is used for regenerating the desiccant. The system alternates between towers to ensure continuous operation.
Installation: The dryer is wall-mounted with all components pre-assembled. A pre and after filter kit is included to protect the desiccant bed and downstream components.
Performance Data:
  • Tables provide inlet and purge flow rates at different temperatures and pressures.
  • Capacity correction factors are provided for different inlet pressures.

LHA Series Dryers The LHA Series Heat–Les™ Desiccant Air Dryer will protect process and pneumatically operated equipment from the potentially harmful effects of moisture that are present in typical compressed air systems. LHA Series Dryers will produce pressure dew points of ISO 8573.1 Class 1 (-100°F, -73°C) and Class 2 (-40°F, -40°C) and guarantee flow rates from 7 scfm to 50 scfm (12 nm3/h to 85 nm3/h), thereby protecting air systems that are exposed to below freezing temperatures. The LHA Series Dryers incorporate a time proven design, with superior features and reliability, in a compact...
