FOCSWATER.C Water cooled screw chiller 

Multiple applications

Standard chilled water applied for HVAC system;

By adopting brine or glycol solution, the outlet temperature

of evaporator can be in the range of -8~12oC, either for ice

storage application or for industrial process purpose;

Heat recovery function is optional.

Safety of electrical devices

Inner structure of electrical cabinet, electrical components and

circuit layout are designed according to EN60204-1/IEC204-1

standard. Controlling power is separated from main power 

by transformer so as to protect from impact and interfere

of electrical current. The power section uses a bar-type

distribution system and interlock-door mains isolator for safety

and reliability. Each load of compressor is equipped with its own

overload protector, fuse and contactor. Electric elements are

with features of excellent insulation, dust-proof and humidity

proof, and suitable for various inferior environments. Electrical

system of the unit is in compliance with EMC code.

UNIT FEATURERS

Compressors

Semi-hermetic screw compressors specifically designed for 

R134a & flooded evaporation application, featuring in high

efciency and energy saving.

Precisely manufacturing technology and least moving

component result in reliable performance and simple

maintenance.

The compresso r , w i t h i t s own capac i t y regu la t ing

electromagnet ic valve and sl ide valve together with

Climaveneta's micro-computer controlling system, can adjust

load output automatically according to the requirement of 

processing, realize 10~100% stepless of precision variable

adjustment and reduce power consumption.

Dedicated Flooded Evaporator/

Condenser 

Flooded evaporator/condenser 

with integral rippled tube are

modied to enhance the initiation

of nucleate boiling sites and

surface area, improving turbulent

flow, resulting in increasingly

overall heat transfer coefficient

and high unit efciency.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 efciency.

Chilled water inside tube make maintanence work convinient

and simple.

Maximum Reliability

Design, manufacturing, testing comply with the several

regulations such as AHRI, EN, UNI, JIS and Chinese standard

GB/T18430.1.

The built-in 3 stages oil separator and external efcient second

separator ensure the constant presence of oil inside. Besides,

unique device is designed by CLIMAVENETA dedicated to

guaranty oil return.

The unit has been charged with R134a and oil before shipped

out from factory, and tested and inspected strictly according

to UNI9218 standard. Only after water and electrical power 

being connected on site, the unit can be put into production for 

providing chilled water.

Optimized and Efcient PartsThe 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, uctuation-free regulation, and therefore a highly accurate

adjustment to the swings of load and ambient conditions.

Economizer has been adopted to improve unit efciency.

FOCSWATER.C Water cooled screw chiller 

● Friendly interface

Fully computer-controlled with no necessity of person duty;

Objective user operational panel with multiple windows clearly

displaying parameters of different categories;

Graphical symbol inputting and displaying with convenient

operation;

Convenient adjusting and setting of data input through menu

and fast key combination.

● Control functions of the unit

The unit adopts W3000 intelligent microcomputer control

system with setting, adjusting and controlling functions, such

as: stepless regulation of cooling capacity; inlet/outlet chilled

water temperature regulation; Starting, unloading and stopping

functions of compressor; starting delay function of compressor;

time limiting function of each hour start of the compressor;

operation timing function of compressor; and running time

balance function of compressor.

● Protecting and alarming functions of unit

Self-test when power on to avoid running with problem.

Three lever password protection to prevent from mal-operation

of persons without authorization.Overload, overheat and overvoltage protection and alarming

of compressor; high discharge temperature protection and

alarming of compressor.

Water antifreeze protection, antifouling protection and alarming

of evaporator;

Protection and alarming of over high and low chilled water and cooling

water temperature; protection and alarming of low water ow;

Protection and alarming of low and high pressure of refrigeration

system, and alarming of refrigerant leakage.

● Fault processing function

 Automatically functioning protection of acousto-optic alarming,

load reducing of compressor, stopping of compressor and

stopping of unit according to each fault grade. Automatically

identifying fault and instructing fault category.

 Automatical ly recording fault with record capacity as much as

200 faults.

Black box function which automatically record on-site state and

all data of fatal fault for providing analyzing data.

Group Control Device

 A group composed of var ious hydronic units permits better 

management for the lowest running cost.

Coordinating the units for optimized operating times assumes

fundamental importance and provides signicant advantages in

terms of reliability (e.g. the compressors) while also permitting

energy savings and delivering water ows constantly at the right

temperature without uctuation.

Resources are always used according to the user 's

requirements without needless compressor cycles or power 

absorption peaks. The unit pumps are intelligently managed.

The number of hours of operation is balanced for more efcient

maintenance.

Resource priority assignment gives precedence to the unit with

greater efficiency: such as chillers with free-cooling function.

The stand-by mode grants response to possible peaks in load.

The elevated characteristics offered by the serial interface

keypad are the highest currently available in the market.

Convenient application and maintenance

Fully computer controlling, menu displaying, self-checking

of unit, running, load adjusting and safety protection are all

completed by computer control system. Daily operation is onlyto switch on starter. Multiple refrigerating systems are available

for standby equipment. The unit is available of functions such

as fault protection, memorizing and alarming. All faults are

clearly displayed. Each return circuit has inspection valve with

"pump down" function which is convenient for repairing.

FWS3000 Field Web Server 

Device for supervising Climaveneta units. Supervisiontakes place via a direct link with the computer or via

LAN: hence this option can also be managed through

internet resources thanks to the built-in webserver and

the availability of suitably dened graphical pages.

Thus the resulting supervision does not entail installing

any additional software on the computer and, moreover,

employs the most common types of browser; this means

any networked computer can be used.
