Used LAUDA K4R #145142 for sale

LAUDA K4R recirculating chiller and heat exchanger is an efficient, reliable and cost-effective solution for cooling applications in laboratories and industrial processes. This chiller and heat exchanger utilizes a closed loop, 3-stage equipment in order to achieve precise temperature control in a wide range of applications. K4R features a high-efficiency, interior-mounted circulation pump connected to a hermetically sealed compressor. This sealed compressor circulates refrigerant to an integrally mounted heat exchanger, which utilizes direct heat transfer to cool a system. The low-noise operation of LAUDA K4R is achieved by an oversized flywheel combined with a reduction gear. The flywheel helps to keep the unit quiet and minimize mechanical wear and tear. K4R can be adjusted to operate in temperatures between -40°C and +40°C with a resolution of 0.1°C. A microprocessor-controlled PID is integrated into the machine and it has a +/- 0.1°C stability over the entire temperature range. The temperature precision can be enhanced by using an internal temperature probe or an external temperature sensor. LAUDA K4R's efficient, low-temperature operation is made possible by a hermetically sealed condenser and evaporator. This design minimizes the amount of refrigerant used in the tool and provides an improved level of resolution and control. This asset is further enhanced by a computer-controlled dynamic defrosting cycle which automatically defrosts the evaporator. K4R also features a modular model design that allows users to install multiple units in a single location. In addition to providing a cost-effective solution, this feature also improves the equipment's thermal performance and stability. Finally, LAUDA K4R is equipped with advanced safety features to improve its operation and protect the user and environment. This includes safety valves, pressure gauges for efficient detection of pressure levels, and emergency shut-off systems for protection against any electrical or mechanical damage. K4R enables a degree of control and efficiency that is unmatched in similar models. This makes it an excellent choice for use in laboratory and industrial applications that require precise cooling.
