Afshin Exciting news from TECA’s Cold/Hot Plate and Liquid Chiller product lines- the newest version of tecaLOG data logging/controller software has been launched. For use with the integral PID temperature controllers of the Air-Cooled and Liquid-Cooled Laboratory Cold/Hot Plates as well as the Bench Top and Rack-Mounted Liquid Chillers, tecaLOG is designed to be easy to use and offers many advantages to the end user.
TECA now offers eight air conditioners for enclosure cooling which accept 48 vdc input voltage.
TECA’s new Stirring Bead Bath can maintain samples from 0 °C to 50 °C using reliable, low maintenance thermoelectric (Peltier) technology.
TECA now offers a 690 watt product with a 13.3 x 20.3 inch flat plate surface for heating and cooling. See New, Even Larger AHP-5400CPV!
TECA Corporation has introduced a new enclosure cooler series. The AHP-2259 Series of thermoelectric air conditioners features universal input voltage. Designed to run off of 100 to 240 volts AC, the units can be easily utilized anywhere. There is a high-efficiency version which provides 1330 BTU/hr of cooling with a C.O.P. rating of 1.35. For more cooling, the high-capacity version is capable of 1820 BTU/hr (C.O.P. rating is .65). Both versions include the energy-saving ECO-Mode for passive cooling during lower demand times. Heat/Cool or Cool-only configurations are available. End users can specify NEMA-12 or NEMA-4 as well as temperature control options.

Coldest Liquid Cooled Plate Updated with PWM Temperature Controller
TECA’s liquid cooled cold/hot plates, the LHP-1200CPV (single stage) and LHP-1200CAS (two and three stage cascade system) 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.
TECA Model AHP-1801XPHC-1 Thermoelectric Air Conditioner is used to enable the safe installation of a gas chromatography system into hazardous locations. Most installations are rated Class 1, Groups C & D, Division II. However in some cases the installations require Group B and/or Group A. TECA’s AHP-1801XPHC-1 maintains the interior of the Process Analyzer Enclosure at a control temperature of around 70o °F. It meets the various requirements of all the installation environments.
This system is installed in Refining, Petrochemical, Upstream and other applications requiring the aforementioned safety ratings. Controlling the temperature of the equipment enclosure rather than the entire shelter allows for far more economical plant installations even in very cold or very hot environments.
Our customer reports:
“Simply protecting our Process Analyzer Enclosure from direct sunlight and precipitation is enough using the AHP-1801XPHC-1. The TECA Air Conditioner has plenty of capacity to handle the most demanding environments such as the Texas Gulf Coast and even in Alberta, CA. See the actual plant installation picture where 3 Process Enclosures are shown. The TECA Air Conditioners are clearly evident below each analyzer. These units have been in operation for more than 2 years without maintenance, without downtime. This says a lot about the capability and capacity of the TECA product in a tough environment. And the analyzers have performed flawlessly delivering control quality composition data to the plant process control computer.
A manufacturer of specialty materials required cooling and heating of small enclosures. The system pictured here is used for the mixing of helium and hydrogen with dew point control.
TECA Model AHP-301FFHC is used with a TECA PID temperature controller to regulate the temperature of the enclosure in order to establish the moisture content of the “wet gas”, which is blended with dry gas to fix the dew point by way of the Buck Equation.
The customer is pleased with the results and continues to build more systems using TECA air conditioners and temperature controllers.
the AHP-301FF series is now replaced by newer model the AHP-401 series.
