Additional Information

N/A Utilizing the latest technological advancements, HES Series refrigerated dryers offer a new way of thinking and an innovative approach to efficiently treat compressed air.

In a typical manufacturing facility, up to 30% of electricity consumed is for generating and treating compressed air. To reduce total cost of operation and qualify for utility company incentive programs, proper air treatment equipment selection and application is required.

Saving Energy is a Global Priority

N/A Compressed air users world-wide are integrating energy management best practices into their operations, with the goal of reducing power consumption and lowering their energy costs.

Demonstrating our commitment to continuous development of sustainable solutions, the HES Series significantly lowers total cost of operation by consuming electrical power (kWh) in direct proportion to real-time demand.

Meeting The Needs of Today and Tomorrow

N/A We believe our customers are partners in the innovation process. Insight is continually gathered to understand the end-user experience of today and gain vision to the opportunities of tomorrow.

Measurable Energy Savings

N/A In a typical manufacturing facility, up to 30% of electricity consumed is for generating and treating compressed air. To reduce total cost of operation and qualify for utility company incentive programs, proper air treatment equipment selection and application is required.

Load Matching Performance

N/A Compressed air load profiles in most manufacturing facilities fluctuate. The HES Series provides cost-effective energy savings by matching electrical power consumed in direct proportion to incoming air demand. Near linear load matching is achieved from 0 to 100%.

Digital scroll refrigerant compressors precisely match inlet heat load on the dryer with the required input power...No more...No less.

Innovation By Design

Sustainable Energy Saving Solutions	N/A To maximize full energy savings potential, refrigeration systems are designed with digital scroll compressors that load and unload based on real-time air load demand. Less energy is consumed during periods of unloading, delivering proportional energy savings Rugged design is compliant to ingestion of liquid and solids, enables non-compressible substances to pass freely though the compressor All models utilize environmentally friendly R404A refrigerant, recognized globally as an efficient and safe HFC solution
Engineered for Premium Performance	N/A Compressed air is chilled to the specified pressure dew point in stainless steel brazed plate heat exchangers, offering corrosion resistance for the life of the dryer. Each plate is press formed with chevron patterns, creating turbulent flow, providing a self-cleaning effect Smooth, non-fouling stainless steel surfaces promote low resistance to flow, improving system efficiency Heat exchangers are fully encapsulated in non-degrading insulation to maintain thermal efficiency
Advanced Cabinet Design	N/A The unique cabinet construction enables 360-degree access to critical components. Cam lock panel removal provides trouble-free entry for routine maintenance Baked polyester, powder coated cabinets withstand harsh environments and maintain long-term visual appeal Inlet and outlet connections are located on top of the dryer, promoting ease of installation
Clean, Dry, Filtered Air	N/A HES series dryers are self-contained air treatment stations, furnished with integrated high performance filtration. Meets ISO 8573-1: 2010 Air Quality Class standards for particle removal, pressure dew point and remaining oil All dryers are equipped with two stage separation to remove solid particulate 3.0 micron and larger, with remaining oil content of 5.0 mg/m³ Delivers ISO Quality Class 3- Solids; Class 4- Oil Optional cold coalescing filters capture solid particulate 0.01 micron and larger, with remaining oil content of < 0.01 mg/m³ Delivers ISO Quality Class 1- Solids; Class 1- Oil
System Protection on Demand	N/A No-air-loss, level actuated demand drains efficiently remove condensate from the system, without loss of compressed air. Condensate drain lines terminate at discharge connections conveniently located on the side of the dryer Drain assembly is equipped with an isolation valve and strainer to optimize service Push to test button located on the operator interface enhances system reliability
Best-In-Class Warranty	N/A As an extra measure of protection, Hankison® offers an extended warranty beyond the standard 2 year coverage. Purchase an HES maintenance kit on an annual basis and receive 3 additional years of protection, parts and labor

Customer Driven Solutions

Energy Management Monitor (EMMConnect™)

N/A HES Series dryers are equipped with EMMConnect™ controls to monitor system performance, manage operation of the digital scroll compressor and track energy savings.

The operator interface features a membrane touch panel, with diagnostics communicated in a user-friendly text display. A bank of light emitting diodes operate sequentially providing indication of dew point temperature in real-time.

Advanced, User Friendly Control
