Modern temperature control systems need more than just cooling performance. Users also need intuitive controls, remote access, system visibility, and the ability to integrate chillers into larger automated processes. That’s where the software behind the Ascent Ultra-Low Temperature Chiller becomes a major advantage.
The Ascent control platform is designed to simplify operation while still providing the flexibility needed for demanding applications like thermal vacuum testing, environmental simulation, aerospace testing, botanical extraction, semiconductor manufacturing, and laboratory process control.
Simple Control for Daily Operation
The Ascent interface gives operators direct control over core system functions from the touchscreen HMI. Users can:
- Power the entire system on or off
- Independently control the pump for fluid circulation
- Reset alarms and over-temperature conditions
- Adjust temperature setpoints
- Schedule temperature changes throughout the week
The programming interface allows users to create timed temperature schedules by selecting the day, time, and desired temperature setpoint. This makes it easier to automate recurring thermal processes without requiring constant operator interaction.
Real-Time System Visibility
During operation, the Ascent home screen provides continuous visibility into system performance, including:
- Temperature readings
- System status
- Active alarms
- Operating conditions
For troubleshooting and diagnostics, the Refrigeration Circuit screen provides deeper system information, including:
- Superheat
- Subcooling
- Liquid temperature
- Evaporator temperature
- Refrigerant pressures
This level of detail allows technicians to quickly identify operating issues and better understand overall system performance.
Remote Access and Connectivity
One of the biggest advantages of the Ascent software platform is connectivity flexibility.
Users can connect directly to the chiller through its built-in Wi-Fi network using a phone, tablet, or computer. Ethernet connectivity also allows remote access through the system IP address for monitoring and control across a local network or facility infrastructure.
The controller platform supports multiple communication protocols, including:
- BACnet IP
- BACnet MS/TP
- Modbus TCP/RTU
- MQTT
- RESTful API
- HTML5 dashboards
This allows the chiller to integrate with building management systems, PLCs, automation platforms, and custom process controls.
Integration with LACO’s HVC-3500 Thermal Vacuum Controller
For applications requiring more advanced automation, the Ascent chiller can integrate with LACO Technologies HVC-3500 Thermal Vacuum Controller.
While the standard Ascent interface focuses on direct chiller operation and scheduling, the HVC-3500 expands system-level automation capabilities with:
- Adjustable temperature ramp rates
- Multi-zone temperature control
- Automated vacuum and thermal recipes
- Integrated vacuum gauge and valve control
- Pump sequencing and interlocks
- Data logging to USB, Ethernet, or Micro SD
- Up to 20 configurable recipes
- Automated evacuation, vent, and hold sequences
The HVC-3500 is especially valuable for thermal vacuum systems and complex environmental testing processes where temperature control must coordinate directly with vacuum conditions and other system hardware.
