AIR/WATER HEAT EXCHANGER WITH 5 or 10 kW cooling performance
For applications requiring a fully enclosed cabinet, nVent SCHROFF offers a cost-effective cooling solution with the new LHX 5 kW and 10 kW air/water heat exchanger including control unit. The tandem development of the air/water heat exchanger with a control unit tailored to the Varistar CP cabinet platform ensures optimal performance.
The Varistar CP LHX+ Electronics Cabinet is perfectly suitable for applications if:
The demand for precision testing is rising due to:
The higher complexity of test objects
Handling of multi-sensor technology
Decentralized set-up is required:
To position equipment closer to measurements
For edge computing applications
Key Benefits:
Space-Saving & Modular Cabinet
Available starting at 600 mm W x 800 mm D footprint per cabinet. Including EMC and up to IP55 protection.
Scalable Cooling Performance
Adopting from 5 kW to 10 kW during operations, while infrastructure in the cabinet stays the same.
Precision Control
Controller with precise temperature regulation accuracy of +/- 0.1°C.
Greater Productivity, Higher Safety
Heat exchanger control directly at the cabinet or via remote access control
Complete Solution Offering
19" EMC cabinet, with in-rack air/water heat exchanger in the lower section, multiple sensors, and control unit in the upper section, providing precise temperature control and remote access.
- Standard configurations on-stock
- Change rack size, accessories, and branding based on your individual needs
- Air/Water Heat Exchanger as retrofittable piece part available
- Includes remote access for one or multiple racks
Varistar CP Electronics Cabinet
Modify your rack to your needs
With the modular Varistar CP electronics cabinet platform, you can choose from 100 cabinet dimensions, a variety of off-the-shelf components, EMC compliance, and IP 55 protection.
The cabinet can be placed in a decentralized location and in a dusty and unmaintained environment (e.g. a tunnel). With its size of only 600 mm W x 800 mm D it provides a reduced footprint.
Cabinet dimensions 600 mm W x 800 mm D or 600 mm W x 1000 mm D
Lever handle locks with 333 profile half-cylinder
Effective cable ducting without negative effect on High IP or EMC functions
Air/Water Heat Exchangers
Scale up your cooling performance
The cooling capacity can be increased during operation without adapting the infrastructure inside the cabinet. A single fan with 5 kW cooling capacity can be exchanged for a double fan unit with 10 kW cooling capacity.
You can upgrade the cooling performance easily, which reduces the required installation work to a minimum. It also reduces OPEX as scaling up can be achieved through hot swaps.
Key features:
- Easy to mount and retrofit
- Front to back cooling
- 19" heat exchanger installed in the lower cabinet section
- Scalable cooling performance
- Double fan unit for 10 kW cooling performance
- Single fan unit for 5 kW cooling performance
- Strict separation of cold and warm exhausted air
- Cooling is close to equipment; quick regulation water and air volume flow
- Power supply with a wide range
- 240 V as standard
- 115 V on request
Cooling Concept
- The fans can be exchanged without having to replace the heat exchanger
- Air flow volume of ~ 1000 / 1800 m³/h
- Water flow temperature from 6°C to 25°C
- Ambient temperature from 5°C to 50°C
- Temperature can be regulated manually with the remote on the door
- Temperature can be regulated remotely through a central management system connected via Ethernet / Modbus / Web Server / SNMP
- Heat exchanger shuts off when the door is opened
Monitoring
Monitor via Remote Access
The high-precision temperature control of the LHX+ is realized via a likewise modular control unit with the option of remote monitoring and remote control. The temperature can be controlled via a door-mounted terminal with a display and keypad as well as remotely via Ethernet access and web interface.
Whether minor or major adjustments to the controllers are required, the electronics cabinet does not need to be opened.
