The Freeze / Thaw TH series chambers are our state of the art freezer environmental chambers used for a variety of applications. Freeze-thaw chambers are excellent for customers requiring ramp/soak programming. Controls are able to be quickly exchanged for future upgrades or repair.
Darwin Freeze Thaw (TH) chambers allow you to determine if your product will remain stable under various conditions. During the freeze thaw cycle your product is put through a series of extreme temperature changes that it may encounter during its life cycle. Versatility with the chamber includes varying the freeze and thaw temperatures, duration in the freeze and thaw parts of a cycle, and overall number of cycles per day. These Freeze Thaw chambers are ideal for ASTM materials testing, as well as testing for drugs, food & beverage, and personal care products. They exceed ICH/FDA guidelines concerning uniformity requirements with a temperature range of -25°C to 50°C. Approximate ramping ability is as follows 1°C per 2 minutes from -23°C to +23°C and back, unloaded. Note: Some defrost tolerance may be required for extended operation (more than 48 hours) below 4°C.
The TH series allows for testing in accordance with the AASHTO T103 Test Method, Procedures A, B and C. Additionally, Darwin’s Freeze Thaw chambers allow for testing in accordance with the Iowa Department of Transportation Test Method 211-B.
Standard controllers for the TH Series are manufactured by Fuji Electric and are ideal for laboratory freezer. Unlike many proprietary controllers, this controller is commercially available and proven in tens of thousands of installations. Standard functions include: autotuning, fuzzy logic, PID control, programmable alarms, calibration capability, offset capability, etc. A touchscreen control interface is optional. Other controller manufacturers are also supported (Watlow, Allen-Bradley etc.)
The TH Series freezers utilize less energy than comparable freeze thaw chambers and introduce less impact upon building cooling systems. This efficiency “dual benefit” allows our chambers to be located in spaces unsuitable for other chambers.
We offer technical support throughout the lifetime of your freezer. In addition to standard warranties, we also offer extended warranties for cooling components, parts and labor. We also provide qualifications, validations and preventive maintenance services at an additional cost. Please ask for a quote.
The TH Series provides an oversized and balanced, environmentally friendly R404A refrigeration system, epoxy coated evaporator, large evaporator and coil heater permit for a short defrost cycle. Along with an automatic evaporator fan morto to delay frost during defrost.
The TH series freezers utilize quiet, highly efficient DC fans.
Data Logging, Chart Recorders, Touch Screen Control Interface
Standard model features stainless door, front, and brushed aluminum sides. Interior has coated aluminum side walls, door liner, and back with stainless steel floor and ceiling.
2" I.D access port with access port cover and insulation plug located on side wall of the chamber.
Positive seal, self-closing doors (gravity cam-lift) with 120 degree stay open feature. Door gasket removal and installation is tool-less. Glass door models feature double pane,"Low-E" glass.
Entire cabinet structure and doors insulated using foamed-in-place CFC-free polyurethane foam.
Wire shelves (3 per door) available in stainless steel or PVC coated. Shelves capable of supporting up to 150 lbs. Gray PVC coated shelves are standard.
Full height shelf support pilasters, with double oblong holes on 1/2" centers. Pilasters made of the same material as cabinet interior. Four (4) chrome plated, stainless steel shelf clips to be included for each shelf.
Refrigeration system factory balanced using CFC free 404A refrigerant.
Top mounted condensing unit.
Factory pre-engineered capillary tube system with oversized condenser and evaporator to reduce product pull down time and to consistently maintain interior cabinet temperature (non-adjustable capillary tube system superior to problematic expansion valve).
Evaporator – epoxy coated at the time of manufacture to eliminate the potential of corrosion.
