The Armfield HT10XC is a service unit, which can be used in conjunction with a range of small scale accessories for a wide range of demonstrations into the modes of heat transfer. The factors that affect heat transfer can be investigated and some of the practical problems associated with the transfer of heat can be clearly demonstrated.
The heat transfer accessories may be individually connected to the HT10XC service unit, which provides the necessary electrical supplies and measurement facilities for investigation and comparison of the different heat transfer characteristics.

A specific feature of the HT10XC is that it incorporates the facilities and safety features to allow the accessories to be remotely controlled from an external computer, where this is appropriate. With suitable (user provided) software, this means that the equipment can be operated remotely, for instance over an intra-net or even over the internet. All the facilities can also be accessed locally using the front panel controls and display.

HT18C Thermo-Electric Heat Pump - Issue 1
	Based on a Peltier device, the Armfield HT18C Thermo-electric Heat Pump demonstrates how electrical power can be used to extract heat from a cool surface and transfer it to a hot surface. This effect is becoming widely used for point cooling (e.g. of semiconductor devices) and small scale volumetric cooling. The HT18C is designed for use with the Armfield HT10XC Heat Transfer Teaching Equipment.

HT30XC Computer Controlled Heat Exchanger Service Module - Issue 2
	A range of small scale heat exchangers, designed to illustrate the principles and techniques of indirect heat transfer between fluid streams. Different types of heat exchanger can be mounted on a common bench-top service unit. Small scale versions of commonly used industrial heat exchangers are available (including plate, tubular and ‘shell and tube’) for analysis and comparison. The equipment is controlled by a user supplied personal computer, which serves as the operator interface. Full data logging, control and educational software is supplied with the equipment. In addition, the equipment has been fitted with failsafe systems, including a watchdog circuit, which allows for safe operation from a remote computer.
