Preci-Max Rollers | 5 TR Air Chiller for Roller Heat Treatment

Customer: Precimax Roller
Product Supplied: 5 TR Variable Speed Air Chiller
Application Objective: Roller heat treatment – supercooling process

Background

Precimax Roller specializes in precision roller manufacturing, where consistent temperature control is critical during the heat treatment and cooling stages. To improve the efficiency of their roller supercooling operation, they were seeking a reliable and energy-efficient cooling solution.

Problem

Earlier, the plant was operating on a wet conveyor process without any heat recovery system.
This setup resulted in:

• High energy losses due to inefficient cooling.

• Inconsistent roller temperature during processing.

• Excess water consumption and moisture issues near the conveyor area.

• Increased operating costs and maintenance requirements.

Solution by Himalaya Refrigeration

Himalaya Refrigeration provided a 5 TR Variable Speed Air Chiller specially designed for roller heat treatment supercooling.
The system was integrated with a dry conveyor process, along with an in-built heat recovery arrangement to maximize efficiency.

Key features implemented:

• Variable Speed Drive (VFD): Automatically adjusts compressor speed as per load, ensuring energy savings.

• Heat Recovery System: Utilizes waste heat effectively, minimizing overall power consumption.

• Dry Cooling Process: Eliminates water wastage and moisture-related issues.

• Precision Temperature Control: Maintains uniform cooling for better roller hardness and quality finish.

Benefits Achieved

• 30–35% energy savings through VFD and heat recovery combination.

• Zero water consumption compared to earlier wet cooling system.

• Improved roller quality and consistency due to precise temperature control.

• Reduced maintenance and longer equipment life.

• Environment-friendly and cleaner operation in the production area.
