Thermodynamic engineering: Plant engineering

HAPRO produces turnkey installations in the field of thermodynamic engineering for almost all industries. Every installation is individually designed and built by our specialists according to customer specifications, whether as a complete installation or as part of an existing one. Thermodynamic systems create advantages in many automated production processes. Hot air works quickly, accurately, safely and, above all, cost-efficiently.

Preheating system for sensors

Application: Sensors must be heated to exactly 82 °C +/- 1K for fine tuning and must then maintain this temperature.

The requirements for the mechanical design were very tough. In addition, tremendous precision was required in transporting the sensors and, above all, the temperature had to be maintained within +/-1K.

Installation concept: Five interlocking heating chambers, each with its own hot air supply and temperature control. In the lead-in to the chambers, the sensors are heated to 82 °C before being transferred to the heating chambers.

Shrink-fitting machine for cables and heating cables

Application: Cable ends must be shrunk and crimped.

Installation concept: Recirculating system with workpiece carriers and a shrink tunnel with an automatic pressing unit. PLC-controlled, manual loading of the products with shrink tubing, automatic program-controlled shrinking the shrink tubing including crimping.

Bottle heating including a cooling section

Application: Bottles (from bottle production) must be tempered.

Temperature window: Heat the product from approx. 60 °C to 120 °C within approx. 60 seconds.

Installation concept: approx. 6 metre-wide thermal bridge with a length of approx. 2. 2 m in accordance with customer specifications, including motorised height adjustment

Completely PLC controlled, 10 air heaters with 18 kW each (max. blow-out temperature 450 °C) together with 10 fans, including cooling section;

Test system for exhaust gases

Application: an air/gas mixture must be controlled to a certain temperature for a measuring stand to enable the gas content to be determined exactly.

Installation concept: a combined air heater and switch cabinet was manufactured to match the customer's existing test bench.

The control system is computer-assisted via a control station. Depending on the configuration of the switch cabinet, it may be with or without fan control and with differing heating outputs – for test laboratories all over the world.
