FLUID DISPENSING

Fluid Dispensing:

A leading manufacturer of fluid dispensing systems uses one of our Thermoelectric Cold Plate and Temperature Controller for controlling the fluid temperature of adhesives, sealants, lubricants and other materials in meter, mix and dispensing systems.
Unlike other larger, higher cost and less accurate heating and cooling devices, which use heater cartridges, refrigerant or water to heat and cool, these thermoelectric-effect temperature controllers use the Peltier-Seebeck effect to directly convert electrical voltage to thermal differentials. This effect, which is reversible, either heats or cools fluid materials with precision to the temperature set point. The compact Peltier thermoelectric device, temperature sensor and the temperature control is mounted to a manifold where the fluid passes through to be precisely heated, maintained or cooled.

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 FLUID FLOW

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.

R & D LABORATORY

An R&D laboratory needed to quickly cool beakers of high-concentration sucrose samples to 10 °C.  The customer reports that using TECA’s AHP-800MSP Magnetic Stirring Cold/Hot Plate system has been successful.

The customer has different sizes of samples, which are accommodated by TECA’s sleeve accessories. The customer uses 2L, 1.5L, 1L and 800mL sleeves at different times with the AHP-800MSP system. The sleeves are easy to switch in and out and add versatility to the system.

In fact, unique to this product is the adjustable nature of many of its features: stir-bar speed, fan speed (for noise reduction), and temperature sensing (internal or external).

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.
