Extraction & Cultivation Cooling

Precision Cooling for Every Stage of Production

Cannabis and CBD operations demand precise temperature control at multiple points in the production chain. Extraction facilities need ultra-cold temperatures for ethanol winterization and solvent recovery. Hydroponic grow operations need carefully controlled root zone temperatures to maximize dissolved oxygen and plant performance.

A water chiller from Rite-Temp addresses both. Every unit is custom-configured to your specific process requirements — flow rates, target temperatures, ambient conditions, and facility layout.

  • Extraction Process Cooling — Ultra-low temperature control for ethanol winterization and solvent-based extraction.
  • Root Zone Cooling — Circulates chilled nutrient solution through hydroponic reservoirs and root zones.
  • Dissolved Oxygen Optimization — Cooler water holds more dissolved oxygen — critical for explosive root growth.
  • Disease Suppression — Optimal root zone temperatures reduce the low-oxygen environments that promote root pathogens.
  • Closed-Loop Efficiency — Recirculating design reduces water and operating costs versus open systems.
  • Scalable Configurations — 1.5 to 10 ton units for facilities of any size.

Why Water Chillers for Cannabis

The Science of Root Zone Cooling

Dissolved Oxygen at the Root Zone

A nutrient solution's capacity to hold dissolved oxygen drops as temperature rises. Chilled root zones maintain high DO levels — directly driving faster growth and stronger root development.

Disease Suppression

Low-oxygen, warm-water environments accelerate root rot and fungal pathogens. Rite-Temp chillers maintain the cool, oxygen-rich conditions that keep root zones healthy.

Closed-Loop Recirculation

Chilled nutrient solution circulates continuously through the system and chiller. As pumps and equipment add heat to the solution, the chiller removes it — maintaining a consistent temperature indefinitely.

Ultra-Low Temperature Extraction

For ethanol-based extraction, the chiller provides the very cold temperatures needed to winterize crude extracts — precipitating waxes and lipids before filtration.

Scalable to Any Facility Size

From a small craft extraction lab to a multi-room commercial grow, Rite-Temp chillers in 1.5 to 10 ton configurations cover the full range of facility cooling loads.

Built to Your Exact Specs

Flow rates, temperature setpoints, pipe sizing, electrical service, and footprint — every Rite-Temp chiller is configured individually. Not off the shelf.

Common Questions

Cannabis Chiller FAQ

How do water chillers support cannabis and CBD extraction?+
Industrial water chillers provide the precise low-temperature cooling required for ethanol and solvent-based extraction processes, including winterization. They also control nutrient solution temperatures in hydroponic grow operations, maintaining optimal dissolved oxygen levels in the root zone for healthy plant growth and disease suppression.
What is the optimal root zone temperature for cannabis hydroponics?+
Most cannabis cultivators target nutrient solution temperatures between 60°F and 68°F. Within this range, the solution holds high levels of dissolved oxygen and remains cool enough to suppress root pathogens. As temperatures rise above 72°F, dissolved oxygen drops significantly and the risk of root rot increases. A Rite-Temp chiller keeps your reservoir in the optimal window regardless of ambient room temperatures.
Can a water chiller cool the root zone in a hydroponic cannabis operation?+
Yes. Water chillers are one of the most effective ways to cool root zone temperatures in hydroponic systems. Chilled water is circulated through the nutrient reservoir or root zone, maintaining temperatures that allow high dissolved oxygen levels — critical for vigorous root growth and disease resistance. Both soil and soilless media gardens benefit from this approach.
What size chiller do I need for my extraction or grow facility?+
Sizing depends on your heat load — the volume of solvent or nutrient solution being cooled, your target temperature, the ambient conditions of your facility, and the heat generated by pumps and lighting. Rite-Temp's new product line covers 1.5 to 10 tons. Call 1.800.462.3120 for a sizing consultation tailored to your facility.
