Daikin EUW10KZW [5/49] Specification text

Specification text

Unit construction

Compact, modular design water-cooled chiller for indoor installation IP20 - manufactured according to the lSO 9001 quality standard.

The EUW-KZW range has been designed for both air conditioning and process cooling applications. The use of state-of-the-art technologies

and high quality materials ensures efficiency, reliability and an extended service life.

Each DAlKIN chiller is subjected to many hours of test runs in the factory allowing for standard requirements.

Casing / Colour

Powder coated, galvanised steel plate. Fully factory assembled on a base frame. Colour ivory white (± RAL 9044) / Munsell code 5Y7.5/1

Number of cooling circuits

Size 5-12 single circuit, 16-24 double circuit.

Each refrigerant circuit has its own independent design thereby guaranteeing a high level of system reliability.

The EUW16-24KZW units have 2 plate heat exchangers (two refrigerant circuits / one water circuit) in order to minimise the hydraulic

installation overhead.

Compressor

One R-407C optimised fully hermetically sealed DAlKIN scroll type compressor per refrigerant circuit. As a design requirement, this

compressor characteristically offers extremely smooth performance, efficiency and operational reliability. Each compressor is mounted in the

unit with vibration isolation and fitted with a compressor motor overcurrent (Klixon).

Condenser

R-407C optimised counter flow plate heat exchanger made of stainless steel, plates brazed gastight with copper, for water and glycol

mixtures. The water pressure may not exceed the maximum permissible operating pressure of 10 bar!

Evaporator

R-407C optimised DX counter flow plate heat exchanger made of stainless steel, plates brazed gastight with copper, for water and glycol

mixtures. A special refrigerant distribution system has been incorporated into the plate duct for optimal capacity of the complete heat

transmission surface. As well as an additional increase in efficiency, this is also responsible for stable control behaviour in the heat

exchanger. The plate heat exchanger is heat-insulated to ensure it is diffusion-proof to prevent any heat loss. Electronic contactor and water

filter as standard. The water pressure may not exceed the maximum permissible operating pressure of 10 bar!

Piping

Consisting of Cu pipe with all the necessary cooling fittings such as:

The plate heat exchanger is cased with galvanised steel.

Safety and control devices

Each refrigerant circuit is fitted with the following safety devices:

High- and low-pressure switch, hot gas temperature monitoring, compressor thermal cut-out, overload relay, frost protection.

Each refrigerant circuit is fitted with the following control devices:

Electronic temperature monitoring, phase-sequence relay, timing safety device and switch frequency limiter.
