CHEMICAL VAPOR DISTRIBUTION SYSTEM

Chemical Vapor Distribution System:

130-tlc-900

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.”

COSMETIC TREATMENT

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.

AIRBORNE THERMOELECTRIC LIQUID CHILLER

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 DUT)

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.

COOLING DETECTORS FOR PIPELINE INSPECTION

Cooling Detectors For Pipeline Inspection:

inspected pipeline cooling detectors for pipeline inspection TLC-900 cooling detectors

 

The maintenance supervisor from an inspection company was experiencing over heating of his detectors which are used in his outdoor pipeline inspection process. TECA’s TLC-900 Liquid Chiller was mounted to the back of his truck to aid in cooling two detectors. The components had been close to over heating without the chiller. Using the chiller with 50 feet of hose, the customer obtained a good result, successfully cooling his components down several degrees (Celsius), to a safer and more reliable operating temperature.

The customer has purchased multiple TLC-900 Chillers for the same use in other trucks. With little maintenance required, the TLC-900 has versatile features such as universal input (100-240 VAC), which is helpful in this application as the customer has inspections in Europe and in the USA. The same TLC-900 Chiller can be used in either locale. A PWM temperature controller offers USB communications, programmable ramp & soak profiles, and fan speed control for noise reduction.

Largest Cold/Hot Plates Updated with PWM Temperature Controller

by

TECA’s largest cold/hot plates, the AHP-1800CPV (single plate) and AHP-1200DCP (dual plates each with independent temperature control) are recently updated to include a new PWM temperature controller. It includes fan speed control which enables the Cold/Hot Plates to slow the fans automatically, reducing noise, as the unit reaches its set point. Another added benefit is that there are now four independent PID settings for different temperature ranges. USB communication port is included and Labview VI examples are available.

Internal Mount a New Option for Air Conditioners

by

When enclosure cooling is needed but space requirements do not allow for an air conditioner to be protruding outside of the enclosure, TECA has a line of “Internal Mount” coolers to do the job. Five new air conditioner series offer horizontal or vertical mounting internal to the enclosure. Performance rating range from 155 BTU/hr to 390 BTU/hr. As with all TECA air conditioners, versions for temperature control and different environment ratings are available. There are no refrigerants or compressors and no moving parts other than the fans. Thermoelectric cooling is reliable and nearly maintenance free, making these new enclosure coolers the perfect solution for remote or hard to access areas.
