Sub-freezing process cooling for brewery crash cooling, solventless extraction, glycol loops, wine cold stabilization, and food processing. Half ton to 30 ton. USA manufactured, UL/CSA certified.
Formerly known as the Deep Freeze Series
The LT Series bridges the gap between standard process cooling and deep sub-zero systems. These chillers are designed for applications that require sub-freezing temperatures — from brewery crash cooling at 28°F to solventless extraction ice baths at 34°F, to glycol loops that need antifreeze protection down to 10°F.
Always use propylene glycol as the heat transfer fluid in LT systems — never pure water below 32°F. Food-safe 30% propylene glycol is recommended for all food and beverage applications.
Size Your System Custom BuildCapacities at 70°F and 90°F ambient. Full spec sheets with electrical and dimensional data available on request.
Capacities at minimum operating temperature (10°F / -12°C fluid outlet). Capacity increases significantly at warmer setpoints. Contact us for full performance curves.
Non-Ferrous Piping
Corrosion-resistant piping throughout for long service life and glycol fluid compatibility.
Sub-Freezing Rated Pump
Pump and wetted components rated for glycol service at temperatures down to 10°F.
Brazed Plate Heat Exchanger
High-efficiency stainless steel brazed plate for maximum heat transfer at low fluid temperatures.
Insulated Lines & Reservoir
Insulated fluid lines and tank minimize condensation and heat gain at sub-freezing setpoints.
Digital Temperature Controller
Precise setpoint control with ±0.5°F accuracy, high/low temperature alarms included.
Multiple Voltage Options
208-240V/1Ph, 208-240V/3Ph, and 480V/3Ph configurations available.

The LT series reaches about 10°F (−12°C) — brewery crash cooling, fermentation, and solventless extraction.
Below about 40°F you run a glycol/water mix so the fluid does not freeze; the concentration is set to your lowest operating temperature.
