LIQUID CHILLER WITH 200′ HOSE

Liquid Chiller with 200′ Hose:

Liquid chiller with 200' hose

A customer wanted a TLC-1400 thermoelectric liquid chiller (Peltier chiller) to maintain a 400 watt load under normal conditions except for one thing, the hose needed to be over 200’ long. Would it pump? How much of an effect would it have on the cooling capacity? We could have run the numbers and come up with an estimate.

It was really easier to just hook up some hose and a constant load plate, roll it into the environmental chamber and see what it did. It did more than it was supposed to. The customers safely bought it knowing it would do what he needed.

COOLING GAS FLOW

Cooling Gas FLow:

A potential customer expressed interest in a cooling/heating system for an aerosol flow tube envisioning a 1 inch OD, 0.875 inch ID stainless steel flow tube mounted inside a 2-2.5 inch ID pipe (likely also stainless steel and insulated on the outside) capable of controlling the tube at temperatures ranging from roughly 5 °C to 40 °C at an ambient temperature of 25-30 °C.  We are measuring the change in particulates in the air due to the temp change.

Standard liquid chillers were first offered along with technical design assistance. The requirements led to direct contact cooling as being a good solution. Standard cold plate products and controllers were offered which led to this request for a custom package. “We would like to have the flow tube sandwiched between the cold plates with the temperature controller and power supplies attached in a similar manner so that we only need attach the temperature controller (the TC-3400 appears as if it will work) to a computer so that we can change the set points remotely.

Is any of this even possible or am I dreaming in Technicolor?” We advised him that the best dreams were in color. Preliminary design work was done and a quote prepared. Shortly thereafter an order was received; design documents were completed and sent to production. Less than 3 months after the initial contact the product was shipped. Several months later a follow up was made with this response.

“Things are doing really well. It does exactly what we wanted it to do, and is much more efficient and better than we hoped for. We’re very happy!

COOLING FLUID FLOW

Cooling Fluid Flow:

A customer needed to cool high pressure flow of fluid in a single pass. Using expanded Aluminum foam and attaching it to the surface of AHP-301CP thermoelectric cold plate (peltier cold plate) provided a way to maximize the thermal contact surface and eliminated the need to complex fluid path and larger cold plate.

COLD WELL

Cold Well:

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.

Cold Wells can be made to accommodate many vessel sizes or the ICE-1200 accessory with TECAlab Thermal Beads works well also.

COOLING PURE FLUID FLOW

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.

CRYOGENIC FLUID CONTROL

Cryogenic Fluid Control:

Cryogenic fluid is extremely sensitive to temperature and pressure changes within an experimental environment. A custom-modified version of TECA’s LHP-300CPHC Liquid-Cooled Cold Plate is installed as part of a system which allows the customer to closely monitor and control temperature.

The long life expectancy and low maintenance requirements of the LHP-300CPHC offer reliability and convenience to the customer’s long-term research experiment.

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.”

COOLING DETECTORS FOR PIPELINE INSPECTION

Cooling Detectors For Pipeline Inspection:

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.
