Full flexibility: the LAUDA Varioflex pump

LAUDA Proline thermostats are fitted with the unique LAUDA Varioflex pump. This high-performance pressure/suction pump can be set to eight different levels to match the current performance requirements, and always enables optimum bath circulation. For devices with deep baths, a Varioflex pump is used as a pressure pump to enable circulation, though in a more powerful version. As a centrifugal pump, the Varioflex pump always offers the right amount of performance, regardless of whether open or closed external circuits are being thermostated. Here, it's not just the performance that is extremely high, but also the extreme energy efficiency. Through its high effectiveness, the energy input into the bath remains low. Through a commuted external electro rotor-motor and the rotational decoupling, it is almost wear and noise free.

The integrated bypass makes the complicated connection of a pump short circuit unnecessary, and improves the bath circulation.
The bypass can be comfortably reached and adjusted with a screwdriver. LAUDA Proline thermostats are fitted with rear and lateral pump connections as standard, for simple connection of external circulation systems. This allows up to two external consumers to be connected simultaneously. For thermostating open tanks, a reverse flow protection can be fitted.

Save energy: Proline SmartCool System for digital cooling management

LAUDA Proline thermostats offer you an energy-efficient digital cooling management system that is unique in its class. The intelligent cooling control operates every mode of operation with the correct cooling performance. It increases or reduces the cooling, in accordance with the status of the current operating requirements. This saves up to 75 % of expensive electrical energy and additionally eases the load to your air conditioning unit: In this way, even in summer you keep a cool head.

Optimum control of the Proline SmartCool System, naturally with automatic compressor control, enables perfect adjustment of the cooling in all modes of operation: This brings more cooling performance and lower temperatures. The advantages of the SmartCool System support with high efficiency programmer operation and automatic temperature changes. The especially high-performance Proline thermostats have a controlled ventilator. This effectively reduces noise production.

A cooling coil for cooling with cold water or brine is already included as standard with heating thermostats. The connections for cooling coil and pump differ so clearly that it is impossible for them to be mistaken for one another. An additional plus for your safety. Alternatively to mains water cooling, a LAUDA through-flow cooler can be connected. A reverse flow protection can be connected for thermostating of open baths.

Heat powerfully and dynamically: Proline PowerAdapt System
Any thermostat is only as good as its energy reserves. The Proline PowerAdapt System makes new forces available: the maximum possible heater output that the mains network permits is used. With that, heater outputs up to 3.5 kW are now possible, even with cooling thermostats – for quicker heating and optimum performance. Nevertheless, the special patented LAUDA heating control, minimises the feedback to the laboratory and the voltage network to good effect, and with that, exceeds the latest legal regulations. Yet another investment in the future.

The safety guarantor: the Varioflex pump
For safety, the Varioflex pump of the LAUDA Proline plays a decisive role. It begins with the material. The LAUDA Varioflex pump is manufactured from a high-tech high-temperature plastic, and is extremely heat-resistant. An additional plus for safety when operating continuously at high temperatures. The second highlight is the conception of the pump motor, which is fitted with modern motor-management. In this way, the pump works with an electrical overload protector and, through continuous analysis of the operational status, also as a low-level protection. Thermostating cannot be any safer.

Double holds better: Low-level protection times two
The low-level protection of the LAUDA Proline is now doubly safe no less. Firstly through the monitoring of the motor rpm: If the pump is running without load, then it is automatically shut down and an alarm is triggered. The second level of safety is carried out via a float. This also records the level and transmits it to the controller. For low level, but just as important for over level, the thermostat recognises the fault.

Everything against overloading and overtemperature
Everything possible is done with the LAUDA Proline to avoid overloading and overtemperature. The system diagnosis is carried out via the SelfCheck Assistant. This is fitted with probes and control units, which avoid all overloads and show faults on the display. A ventilator in the control head of the Master avoids any overheating of the electronics, especially when in continuous operation. Apart from this, it also avoids condensation from heat transfer liquid in the control head. A further useful facility: The overtemperature protection is itself protected against any accidental adjustment.

Also equipped for external control
The modified PID cascades connection of the Proline enables compliance with the desired temperature in the reactor. Together with the additional and relevant proven safety functions, such as supply/return external containment or maximum/minimum value containment for instance, complex control tasks can also be reliably solved.
