High efficiencyThe entire TECS range differs from chillers with screw compressor because of its high performance at partial loads, with an average increase of 60% in ESEER. This result is achieved by using an oil-free magnetic levitation centrifugal compressor combined with a dedicated flooded evaporator.

Water-cooled Magnetic Levitation Variable Frequency Centrifugal Chiller

Integrated part load value (ESEER)Increasingly closer attention is being paid towards the power consumption of air-conditioning equipment. In air-conditioning systems, a chiller only works in full load conditions for a few hours a year. For this reason, “seasonal efficiency” is the truly determining consumption factor.The valuation indices have been adopted that consider usage in part load conditions as IPLV in the United States and ESEER in Europe.

ESEER up to 9.58, and IPLV up to 10ESEER(European Seasonal Energy Eff iciency Ratio): 0.03×A+ 0.33×B+0.41×C+0.23×D● Evaporator temp. leaving at 7℃(constant), condenser water (inlet)

Features and Benefits

A revolutionary heartCentrifugal compressor with magnetic levitation

Compression is obtained by two high-speed impellers, driven by a

continuously variable frequency motor, which deliver the exact cooling

capacity required by the system. Magnetic bearings keep the high-

speed shaft suspended in the air and frictionless. This technology,

derived from aerospace applications, has many advantages:

Part Load (%)

● Outstanding part load efficiency thanks to the inbuilt inverter speed control.

● Oil-free, offering improved performance of the heat exchangers thanks to the elimination of the film of oil which, in

other types of compressor, lies between the coolant and the exchange surface.

● Low vibrations under all operating conditions, and

super low operation noise.

● Centrifugal compressor with built-in continuous impeller

speed adjustment up to 48000 rpm.

● Thanks to their high speed, the impellers have been

miniaturized, thereby reducing the size and weight of

the compressor to just 120 kg.

● Very low current during starting (soft start), 2A instead

of the 500-600 A of a screw compressor with the same

cooling capacity.

A leading-edge miniaturized compressor, featuring magnetic bearings and digital impeller speed control, partial load

efficiency levels that have never been obtained up till now.

Magnetic Bearings

Magnetic bearings and sensors keep the shaft properly centered and positioned at all times.● The magnetic bearings have less than .2% the friction loss compared to conventional bearings

● Eliminates the ability of the oil to contaminate the refrigerant

● Eliminates cost of oil management systems (hardware and controls)

● Increases equipment life through elimination of wear surfaces

Does this Integrated Compressor Design handle a Power Outage? ● Motor becomes a generator

● After the compressor comes to a complete stop, the rotor de-levitates normally

onto touchdown bearings.

● Touchdown bearings are used as a back up bearing system

Dedicated Flooded Evaporator/CondenserFlooded evaporator/condenser with integral rippled tube are modified to enhance the initiation

of nucleate boiling sites and surface area, improving turbulent flow, resulting in increasingly

overall heat transfer coefficient and high unit efficiency.

The evaporator is characterized by low pressure drops on both the gas side and the water

side. The level of refrigerant inside the flooded evaporator is guaranteed by dedicate sensor

level and modulating electronic valve.

Single circuit design even for multiple compressor improves unit part load efficiency.

Electronic Valve(EXV)● The electronic valve is adopted to grant the ideal operation of the evaporator in

all conditions.

● The complete flooding of tubes is granted with a sophisticated detection of the

refrigerant level in the heat exchangers.

● The fast processing of the acquired data allow a quick, fluctuation-free regulation,

and therefore a highly accurate adjustment to the swings of load and ambient

conditions.

● Comprehensive operation and alarm records,

keeping the "black box" function.

● Compatible with the Climaveneta group controller

such as Gr2000, Gr3000 and BMS.

Extremely silent operationThanks to the adoption of the centrifugal compressor with magnetic levitation,

TECS sound power and pressure are the lowest on the market, without peaks

in any of the sound frequency spectrum.
