The CWB-01 cold well was first developed as an AHP-1200CPV custom accessory for the petrochemical industry. It replaced the need to maintain ice baths for the storage of chemicals. It has the advantage of good temperature control in either heating or cooling modes. The temperature of the cold plate can be referenced to the fluid temperature or the remote sensibility feature of the CPV can be used to control based on the actual fluid temperatures.
Cooling Fluid Flow:
Chilling liquids being circulated by a peristaltic pump under ultra-clean conditions. When handling and processing various fluids in laboratory and electronic environments cleanliness is a must. Peristaltic pumps have been developed for the purpose of creating a fluid flow without contacting the fluid itself. TECA developed a liquid chiller to cool fluids, while satisfying the same cleanliness requirements.
The solution, based on our successful cold plate product line, has proven to be versatile and effective. Pictured here is the first prototype of a multiple-pass tube cooler for use with a peristaltic pump. Applications range from laboratory to medical to industrial.
Cooling Pure Fluid Flow:
The customer needed to cool a very low flow rate of a very pure fluid. Passing tubing through an ice bath did not provide close enough and consistent enough temperature control. However by using the AHP-1200CPV with tube chiller option and by determining the optimum set point a consistently cooled flow of the pure fluid was obtained.
Chemical Vapor Distribution System:
An OEM customer integrates TECA’s Model TLC-900 Liquid Chiller into a bubbler system designed to distribute chemical vapor via a carrier gas. The bubbler vessel is filled with the liquid chemical. The carrier gas is bubbled through the vessel and TECA’s TLC-900 Liquid Chiller maintains the chemical at a temperature determined by the end user, to maximize process control. The customer chose TECA’s TLC-900 Liquid Chiller over others because of its heating and cooling capability and the versatility of its universal input voltage (100-240 VAC). The customer’s system is sold worldwide and quality and reliability are key. The customer shared with us: “Before we used TECA products, we had half a dozen failed units over in China that my boss had to fix. I’m talking chillers that have only been in service for less than 4 months. In all, there have been at least ten of them go bad over the years. Some of the current orders we have with you are replacement units for the failed ones. We love your products. You are putting the competition to shame. Keep up the good work.”
Photofacial treatments using intense pulsed light are said to remove spider veins and age spots, but are uncomfortable for the patient. The apparatus shown uses a TECA Model TLC-700 Peltier based liquid chiller to cool the tip of the hand piece which rests on the skin area under treatment. This enhances the comfort of the patient; allowing for a better quality treatment. The chiller is a closed loop system so no water gets on the patient or the instruments. Water temperature is closely adjustable over a wide range.
A customer serving the national security market specializes in remote sensing solutions. TECA Corporation’s thermoelectric, rack-mounted RLC-1400 Liquid Chiller improves the customer’s product efficiency by reliably cooling a laser and high-power electrical components, as part of an airborne system.
Production testing (cooling device under test)
TECA’s RLC-1800 Rack Mounted Liquid Chiller offers powerful cooling as a component in the customer’s testing procedure. The customer, developing testing for a radar system, has a device under test (DUT) which contains cold plates. TECA’s RLC-1800 provides liquid cooling to the cold plates and prevents them from over heating during the process. The RLC-1800 is the most powerful liquid chiller we offer, with 620 watts cooling capacity.
Flue Gas Analysis:
The customer uses the TECA TLC-702HC in a heating and cooling process in a laboratory setting. The customer’s PSA system is removing CO2 from flue gas and drying and analyzing the flue gas. The TLC-702HC is available in 120 or 240 VAC versions. Heat/Cool or Cool-Only configurations are available.
