Hailea HC Series Water Chillers – One Range, Different Sizes

Overview

Hailea HC Series Water Chillers are designed to maintain stable nutrient solution temperatures in hydroponic and water-based growing systems. Trusted by growers worldwide for over 15 years, Hailea chillers are known for their reliability, low noise operation, and excellent value for money.

All HC Series models share the same core technology, build quality, and cooling principles.
The only difference between models is cooling capacity, allowing you to select the correct size to suit your reservoir volume and heat load.

Why Use a Water Chiller in Hydroponics?

Maintaining correct nutrient temperature is critical for plant health. Hailea water chillers help to:

• Keep nutrient temperatures within the optimal range

• Maintain high dissolved oxygen (DO) levels

• Protect root systems from pythium and other root diseases

• Improve overall plant performance and yield consistency

Hailea chillers operate like a mini-refrigerator for your nutrient solution, and are simple to install, operate, and maintain.

Shared Features Across All Hailea HC Series Models

All HC Series water chillers include:

• Pure Titanium heat exchanger
  – Anti-corrosive and safe for nutrient solutions

• Strong metal chassis with modern, clean design

• Low-noise operation, suitable for indoor grow rooms

• Digital temperature controller for precise temperature control

• Environmentally friendly R134a refrigerant

• Designed for easy installation and reliable long-term operation

No matter which size you choose, you receive the same quality, performance standards, and reliability.

How Hailea Nutrient Chillers Work

Water is circulated from the reservoir through the chiller using a compatible pump.
The internal refrigeration system removes excess heat and returns cooled nutrient solution back to the reservoir, maintaining a consistent temperature set on the digital controller.

Cooling performance depends on:

• Reservoir size

• Ambient room temperature

• Heat load from lighting and pumps

• Airflow around the unit

Installation & Setup

Setting up a Hailea chiller is quick and straightforward:

1. Connect a suitable pump to the chiller inlet using flexible hose

2. Connect another hose from the chiller outlet back to the reservoir

3. Secure all connections with hose clips to prevent leaks

4. Ensure adequate air circulation around the chiller for efficient heat dissipation

Maintenance & Cleaning

To maintain optimal performance:

• Clean the chiller after each crop

• Fill the unit with clear pickling vinegar, leave for 24 hours

• Flush thoroughly with clean water before reuse

• Always provide good airflow around the chiller to avoid heat build-up

Choosing the Correct Size

All Hailea HC Series chillers use the same technology.
The correct model should be chosen based on reservoir volume and system heat load.

Tip: If operating in hot environments or running high-power lighting, choosing the next size up will improve cooling stability and extend unit lifespan.

Important Notes

• Cooling performance is tested under controlled conditions (30°C ambient temperature, 28°C water temperature before refrigeration).

• Actual results may vary depending on installation, lighting, pump selection, and ventilation.

• Flow rate depends on the pump used and system plumbing.

• Using compatible pumps and accessories is recommended to ensure optimal performance.

• Insufficient room ventilation can reduce cooling efficiency due to heat build-up.

Summary

Hailea HC Series Water Chillers are all built on the same proven platform.
✔ Same technology
✔ Same quality
✔ Same reliability

Only the size and cooling capacity change.

Simply choose the model that matches your reservoir size and growing environment.
