Normal approach

VICOT approach

This structure is to put colored steel on aluminum profile frame and fix

them with bolts, which is a metal to metal contact. Due to air pressure, the

panels and frame are easy to separate from each other. The appearance is not

a rac ve due to the outside bolts.

In order to avoid such situa on, Vicot developed its maze like sealing

structures to eliminate the metal to metal contact between panel and

framework, reducing air leakage.

The frame is made of aluminum alloy. The panels and frame is sealed

with PVC. The cabinet has no cold bridge. The cold bridge defending ability

reaches European TB1. The special double door sealing ensures air ght

environment.

The thermal conduc vity U(W/m2.k) in the following table is measured under 20K stable temperature differentce.

Op onal accessories◎ Control system is op onal and can be designed according to the clients’ requirements, such as: temperature and humidity control of

supply air and return air, an -freezing control, filter pressure differen al control, fresh air damper and fan motor coordinated control,

indoor/outdoor temperature difference compensa on energy saving control, building management system, etc.

◎ Variable air volume func on

VICOT can use asynchronous three phase motor with characteris c of pressure adjustment and speed change to achieve AHUs’ air flow

regula on and energy-saving by the inverter speed adjuster, which has so starter to reduce the impact to electricity facility and can do

stepless adjustment according to indoor temperature/humidity detected by sensors. Inverter brand can be DANFOSS,ABB,SIEMENS, etc.

According to the design, control-box can be equipped, which has the following func ons: total pressure and delta-star start and stop,

phase/overload protec on, motor overheat/over current protec on, and malfunc on alarm etc.

Note: Unit height = nos. of modules in height×200+K Unit width = nos. of modules in width×200+K

Wet-film humidifier

Dry steam humidifier

It humidifies air through natural evapora on of water. Its basic medium is plant fiber. The plant fiber is sintered to form overlapping

corrugated plate polymer composites a er special process, which have strong water absorp on, good self-cleaning ability, non-toxic,

acid resistance, mold resistance and fire-retardant. Its structure can provide the maximum contact surface with air and body of 1 square

meter has contact area of 500-600m2. When dry air passes the wet-film, water molecules will absorb heat from the air, vaporize and

evaporate, which inceases the air humidity. It can use running water or domes c water. Its features are as floows:

Its process is that filtered saturated steam enters into the humidifier, flows axially in the steam sleeving rods and heats the center

spraying rods by the latent heat of steam for ensuring to spray pure dry steam (without condensed water). Then, the saturated steam

enters into steam water separator chamber through steam sleeving rods; in the chamber is annular baffles; when the steam passed it,

it will rotate and flow upward ver cally to separate steam and condensate; the separated condensate is discharged through the trap.

When air needs to be humidified, the regula ng valve will be opened and dry steam enters into center sparying rod and is sprayed out

for humidifica on.

◎ Cleaning equal-enthalpy humidifica on: wet-film cooling humidifica on,without “white powder” phenomenon.

◎ Short humidifying distance: only wet-film body’s thickness.

◎ High satura on effciency: up to 80%.

◎ Safe and reliable: with an bacterial ingredients, good mold resistance.

◎ Advanced steam water separa on technology and structure, ensuring the separa on completely and thoroughly.

◎ Isothermal humidifica on, high efficiency, up to 95%.

◎ Unique muffler structure, no whistle and noise.

◎ Electric or magnCe c dry steam integra on, achieving precise remote control.

Note: 1. Pre-filter: plate type, 2 inches width of frame, folded washable filter, non-woven fabric materials, filtra on efficiency G3 (80%-90% Arrestance).

2. Medium filter: bag type, 1 inch width of frame, 20 inches length of bag, non-woven fabric materials, filtra on efficiency F5 (40-60% Dust-spot).

3. High medium / sub HEPA filter: ultra-fine glass fiber filter, filtra on efficiency F7-F9 (80-95% Dust-spot).

4. HEPA filter: please contact with VICOT if users want to add sub HEPA or HEPA filter.

5. Filter resistance is between ini al resistance and final resistance. Ini al resistance refers to the resistance when the filter has non-dust pollu on; final resistance

refers to the resistance when the filter has been dust pollu on and needs to be washed or replaced a er a certain me. It is not a fixed value and is determined by indoor

requirements to cleanliness and outdoor air pollu on.

6. VICOT can provide op onal differen al pressure gauge and switch for filter. The pressure switch can control differen al pressure alarm forC alarming.

1. Before installing unit, check unit’s model, parts and appearance, etc. according to manual and packing list. Then, open the

access door and turn blades of fan by hand to check if there is any metal grinding noise; if it is, solve it.

2. Unit should be installed on a flat base, which can be concrete type or made by steel channel and should be 160mm higher than

ground at least. There should be drainage ditch and floor drain around the base, for draining the condensate and sewage. And,

there should be enough space for maintenace.

3. The pipe below of heat exchanger is water inlet and above is outlet. Pipings should have their own brackets for bearing their

weight and avoiding unit to bear load. Install check valve for adjus ng water flow and maintenance, and Y-stainer for filtering

impuri es on the water inlet pipe; install air vent at the highest point of system and drain valve at the lowest point. Due to

nega ve pressure, the condensate pipe should be connected to a U-shaped water trap first and then to the sewer (See diagram

of water seal).

4. There should be flexible joint between unit and air duct. Air duct should have its own brackets for bearing the weight.

5. The power is 380V/50Hz/3Ph. A er electrifying, check fan’s rota ng direc on; if it is reverse, change phase sequence of power.

6. Motor should be connected to power with protec on device. Case of unit should be grounded. Motor of more than 15kW

shoud adopt reducing voltage start.

7. Power controller should have phase protec on and overload protec on.

8. There should be enough space for maintenance.

2. In winter, if the unit isn’t used, drain all water in the heat exchanger and blow the remaining water by compressed air for

an -fros ng.

3. When the unit isn’t used for a long me, close fresh air damper, drain water in heat exchanger, loosen belt, and add lubrica ng

oil.

4. Water in the system must be clean and demineralized water is be er.

About Vicot Group1. Before star ng the unit, check each manual/electric valve.

2. Check fan’s bolts, belt and blades.

3. Check air duct’s valves, water pipings, electric system, controll components and wiring.

4. Exhaust the air in the unit and system.

5. Filters should be washed or replaced periodically.

6. The fan and motor parts should be lubricated regularly according to environmental condi ons.

7. The unit should be operated by professional persons. Check unit’s opera on regularly and remove the abnormal situa on.

8. Ensuring the insula on of ven la on system and water system is good enough.

9. During the using, if there is any damage or aging, like canvas, repair or replace it immediately.

10. In cold area, open the heat resouce 5-10 minutes before star ng the fan in order to avoiding cold air to form ice jam. When stoping

the unit, a small amount of hot water should circulate in the coil to prevent rust and frost.
