HPDry

Product catalog summary

Overview: The HPDry refrigeration dryers are designed for high-pressure applications up to 50 bar(g), with nominal air flows ranging from 1.46 to 119 m3/min. These dryers are part of MTA's comprehensive range for high-pressure needs, offering significant energy savings and operational flexibility.

Key Features:

Energy Efficiency: HPDry operates only when necessary, cycling on and off based on air flow and ambient conditions, achieving up to 80% energy savings compared to traditional dryers.
Flexibility: Available in both air-cooled and water-cooled versions, with options for 50 Hz and 60 Hz, and UL listing. Special approvals are available upon request.
Microprocessor Control: Automatic adaptation to operating conditions with user-friendly digital controls displaying main parameters and alerts.
Ease of Use: Front access to major components and automatic cycling reduce space requirements and simplify operation.
Optimum Dew Points: Thermal storage buffers sudden load demands, preventing dew point spikes, with stainless steel demisters ensuring effective separation.

Technical Specifications:

Air Circuit: Comprises two shell & tube exchangers for air-to-air and water/glycol-to-air sections, with a large buffer tank and circulating pump.
Refrigeration Circuit: Operates only as needed, reducing energy consumption and maintaining constant dew points.
Materials and Design: Stainless steel air-side tubes and a simple refrigeration circuit enhance reliability and ease of use.

Additional Components:

Condensate Drains: Available in mechanical zero-loss, electronic zero-loss, and timed configurations.
Air Receivers: Complements the compressed air network.
Filters & Separators: PureTec filters and PureSep separators for pressures up to 250 barg, with four filtration grades.
Adsorption Dryers: DryXtreme range for extremely low dew points, available in heatless and heat regenerated configurations.
Aftercoolers: CoolPro air and water-cooled aftercoolers for high-pressure applications.

Correction Factors: Tables provide correction factors for pressure dew point, working pressure, air inlet temperature, and ambient temperature to guide accurate selection.

Model Specifications: Detailed specifications for various models, including nominal air flow, absorbed power, air connections, dimensions, and weight.

Compliance and Certification: MTA products comply with European safety directives and are ISO9001 certified, ensuring customer satisfaction.

Contact Information: MTA is represented in over 80 countries, with contact details for offices in Italy, France, Germany, Spain, USA, and Australasia.

Unique air circuit How it works: HPDry’s air circuit is made up of two shell & tube exchangers, one for the air-to-air section, the second for the water/glycol-to-air section. The auxiliary water/glycol circuit features a large buffer tank, which acts as a thermal storage, and a circulating pump. The chilled water/glycol mixture circulates through the shell & tube exchanger, cooling the air to the dew point temperature. When the temperature of the water/glycol mixture increases beyond a set value the refrigeration circuit switches on to replenish the buffer tank, switching off again once the...
