CTA Compact

This Air handling system with energy recovery, recycling, heating, cooling, humidifying and industrial supervision, is an excellent didactic tool to teach students in a hands-on manner about comissioning and maintenance of a instrumented compact air handling system.

Features:

• Blowing and extraction
• Mixing and heat recovery(plate heat exchanger)
• Filtration(medium, high efficiency)
• Heating(hot water or electric coil)
• Cooling(cold water coil)
• Heat recovery(plate heat exchanger)
• Steam humidification
• Sensors (temperature, pressure, hygrometry...)
• Centralized Energy Management system (CEM)

Training activities:

• Analyzing the functions of a air-handling system
• Study of PLC and communication network in a building (CEM)
• Commissioning& Configuration
• Climatic and electrical maintenance
• Analysis of the refrigeration, electrical and air flow circuits
• Energy balance and calculation of the performance ratios
• Forecasting the operating conditions

Key points:

• Professional equipment used in collective buildings
• Customized measurements
• Easy-to-use and friendly supervision software
• Open system to main communication protocols (Ethernet, LonWorks, BACNet, Modbus, KNX)
