Chillers

Used Industrial Process Chillers for Sale

A process chiller is often the quiet workhorse behind stable production. When cooling water temperature drifts, it can impact
cycle time consistency, dimensional repeatability, and equipment reliability. This page highlights industrial process chillers used in
real manufacturing environments, including portable and packaged chillers designed to remove heat efficiently and maintain
steady temperatures under changing loads.

Many buyers land here specifically to support hydraulic presses. Press systems can generate significant heat through hydraulic power units,
oil-to-water heat exchangers, tooling circuits, and plant cooling loops. A properly applied chiller helps keep oil temperatures stable,
protects seals and pumps, and reduces performance drift during long runs.

Why a chiller matters for hydraulic presses

Heat is one of the most common causes of hydraulic performance issues over time. When oil runs hot, viscosity changes, seals wear faster,
and components operate under higher stress. In many press applications, consistent cooling supports:

  • More consistent cycle times during long production runs
  • Stable hydraulic performance by managing oil temperature through heat exchangers
  • Improved uptime by reducing overheating-related faults and accelerated wear
  • Better repeatability in processes sensitive to temperature variation

Portable vs. packaged chillers

Industrial chillers are often described as portable or packaged. Both are self-contained solutions, but they typically serve
different plant needs:

  • Portable chillers: Often selected when you want dedicated cooling for a specific machine or cell, or when layouts change and flexibility matters.
  • Packaged chillers: Commonly used as a stable “set it and forget it” utility for a process loop, with the footprint and controls designed for industrial use.

What industrial process chillers provide

  • Temperature stability: Keeps supply water closer to target, helping reduce drift in heat-sensitive operations.
  • Reliable heat removal: Pulls heat out of the loop under real production load swings and long duty cycles.
  • Process protection: Supports longer component life in hydraulics, heat exchangers, and temperature-sensitive subsystems.
  • Scalable cooling: Enables adding dedicated cooling as production grows or new equipment is brought online.

Common applications beyond presses

Process cooling is used across many industries and equipment types, including:

  • Hydraulic power units and oil-to-water heat exchangers
  • Pressroom support cooling (hydraulics, tooling circuits, temperature-sensitive subsystems)
  • Plastics processing support equipment
  • Welding and laser cooling loops
  • General process water temperature management

Key specs that matter most

Not all chillers are interchangeable. The best results come from matching the chiller to the process requirements. The most important specifications are:

  • Cooling capacity (tons or BTU/hr): Enough capacity to handle heat load without temperature drift.
  • Supply temperature range: The setpoint range your process requires.
  • Flow and pressure capability: Ensures heat transfer through your equipment and piping.
  • Electrical (voltage / phase / Hz): Must match plant power.
  • Connection sizes: Impacts installation and compatibility with existing plumbing.
  • Ambient conditions: Plant temperature, ventilation, dust, and seasonal extremes all affect performance.

How to think about sizing for a hydraulic press

Press cooling needs depend on the hydraulic system, duty cycle, and how heat is rejected today. Some presses use an oil-to-water heat exchanger
where the chiller supports a water loop that removes heat from the hydraulic oil. Others cool tooling circuits or auxiliary systems.
In either case, the right approach is to match capacity and flow to your actual heat load and run profile, not just “rule of thumb” numbers.

If you are pairing a chiller with a hydraulic press, it helps to know the basics of your existing setup: whether you are cooling
hydraulic oil via heat exchanger, process/tooling circuits, or a broader plant loop, along with your target temperature.

Brands and types you will commonly see

This category may include a range of industrial chiller manufacturers and configurations, including air-cooled and water-cooled designs,
and a variety of tonnage sizes. The best chiller is the one that matches your required capacity, temperature stability, and flow/pressure needs.

FAQ

Do I need a chiller if my press already has a heat exchanger?

A heat exchanger transfers heat, but it still needs a reliable place for that heat to go. If you have a stable plant water supply,
the exchanger may be enough. If plant water is inconsistent or you need tighter temperature control, a chiller can provide a steady cooling source.

What is the difference between “tons” and flow rate?

“Tons” is cooling capacity (how much heat the chiller can remove). Flow rate is how much water moves through the loop.
Both matter. Capacity without the right flow can still result in poor heat transfer and unstable temperatures.

What information helps when pairing a chiller to a press?

Helpful details include target temperature, approximate heat load or existing chiller tonnage, required flow and pressure, electrical (voltage/phase/Hz),
and how the press is cooled (oil-to-water exchanger, tooling circuit, or plant loop).
