The price includes professional educational materials, printed refrigeration tables, full catering, and free parking on-site.
Training Pricing ListThe „Chilled Water Units” (Chillers) training is aimed at engineers, installers, service technicians, and operators of industrial refrigeration and air conditioning systems.
Our advanced training is a perfect, practical guide to chilled water technology, commonly used in comfort air conditioning as well as industrial and process refrigeration. The course program uniquely combines theoretical lectures with intensive laboratory workshops on modern training rigs in COCH Kraków.
The course is dedicated to all specialists who deal with the design, installation, commissioning, operation, and maintenance of chilled water units. The curriculum includes a detailed discussion of screw, scroll, and turbo compressors, free cooling systems analysis, hydraulics (safety valves, expansion vessels), control automation (three-way valves), as well as properties and regulatory frameworks for refrigerants (including R134a, R410A, R407C, and alternatives like CO2 R744) and secondary coolants (glycols and corrosion inhibitors).
For companies sending their employees, this training is a reliable way to quickly raise the competencies of staff in the safe installation, precise commissioning, and trouble-free operation of refrigeration plants with chilled water units. The acquired knowledge helps minimize the risk of costly failures and optimize electricity consumption costs.
The condition for booking a place on the training is making a prepayment at least 3 business days before the scheduled start of classes. The price includes professional technical materials, complete technical documentation, full catering (two-course hot restaurant lunch, coffee buffet), and free secure parking at the COCH Kraków headquarters.
