CONDENSING VAPOR

Condensing Vapor: AHP-470CP in Laboratory Reactor Instrumentation

condensing vapor   cooling vapor stream

In a chemical process (catalysis), the customer uses several TECA Model AHP-470CP Cold Plates to condense methanol out of a vapor stream and collect liquid in the 100 mL glass vessels shown. The AHP-470CP offers a convenient small size and is customizable to the end user’s needs.

Please see the “Options” section on the product data sheet to learn more.

CHEMICAL WASTE TRANSPORT

Chemical Waste Transport:

Here’s an application that our engineering crew would love to put into greater use if they could figure out where and how. A specialty gas company called. They wanted to transfer toxic and corrosive liquids from big to small containers for lab use. The process had been taking several minutes with too much wasted product.

They knew because of the conditions a natural head pressure in the big container that they could use a cold plate to cool at the receiving vessel (Ø 1.5″ x 12″ bottle) to create a driving force which moves the fluid.

We didn’t go into the physics of this, we trusted what the customer said and worked with them. When they tried an AHP-1200CP it was fantastic. It turned 4 minutes and a lot of waste into no waste and 40 seconds.

ENVIRONMENTAL CONTROL

Environmental Control:

A municipal waste plant had an emergency requirement for a water drop device (to condense moisture for analysis) to be installed in a smokestack. In this time critical application TECA responded with a custom designed variation of the AHP-150CP thermoelectric cold plate, to be mounted high up in the stack. Working with the customer TECA was able to design and deliver the product in less than two weeks, more than meeting the customer’s timetable.

INDUSTRIAL ADHESIVE COOLING

These folks needed to cool a thick fluid that ends up being gaskets when robotically dispensed. A custom version of our AHP-1200CP fit the bill perfectly. Now the product is dispensed consistently because of the temperature control provided by thermoelectrics.

FLOW CHEMISTRY / OEM PRODUCT

Flow chemistry/OEM products application:

A European company specializing in equipment for the continuous flow chemistry market required extreme temperatures for a new product. Integrating a customized version of TECA’s Liquid Cooled Cascaded Cold Plate made the customer’s product possible: they are able to reach temperatures from minus 70 °C to plus 80 °C.

The customer reports that their new continuous flow reactor allows for the use of flow chemistry in many applications, achieving quicker results safely and with better control.

BEVERAGE COOLER

Beverage Cooler application:

The beverage cooler application challenge was to keep concentrated beverage container located next to a hot water tank cool in a high volume OEM application. TECA has the flexibility and resources to manufacture custom OEM thermoelectric cooler (peltier coolers) assemblies intended for use as part of a customer machine, apparatus, or system. This OEM assembly is made by TECA in production runs in the thousands. It is not ours, so to protect the privacy and identity of our customers we can’t give too many details here.

This assembly is part of a beverage service product which is shipped worldwide by a well known consumer products company. TECA furnishes the cooling “engine” which refrigerates the beverage product to be dispensed, and the OEM builds finished machinery in their own plants.

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.

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.

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.
