Spiral Heat Exchangers by EHTS

We are Manufacturer, Supplier, Exporter (and also Servicing / Maintenance Services Provider) of Spiral Heat Exchangers, Genuine Spares, Spare Parts from Pune, Maharashtra, India.

Eternitive Heat Transfer Solutions India Private Limited (EHTS) designs and manufactures spiral heat exchangers using formable and weldable materials. Our Spiral Heat Exchangers (SPHE) are particularly well-suited for handling sludges, slurries, wastewater, high-viscosity liquids, and those containing fibers and solids. EHTS offers a reliable solution for challenging fluid applications, achieving up to three times the thermal efficiency of conventional heat exchangers.

The counter-current flow design in our SPHE allows for close temperature approaches, providing significant savings in installation, operation, and maintenance. EHTS's Spiral Heat Exchangers can withstand extreme pressures and temperatures, offering a self-cleaning effect ideal for long-lasting, low-maintenance performance.

Technology Overview

EHTS Spiral Heat Exchangers feature a unique single-channel, turbulent flow design that minimizes fouling. These heat exchangers are widely used in refineries, petrochemical, oil, and gas industries due to their thermal efficiency, durability, and versatile design. The single-channel design generates high shear rates, creating a self-cleaning effect that significantly reduces maintenance requirements.

Key Features and Benefits
  • Single-channel design with high shear rates prevents clogging
  • Customizable channel size for optimal flow and media properties
  • Capable of handling aggressive temperatures with customizable materials
  • Hinged covers allow easy maintenance and full access to the coil
  • Compact design with high heat transfer coefficients, up to twice that of shell and tube exchangers
