What is CAV (Constant Air Controller)?

CAV is designed to project air in specific volume not withstanding the room temperature.
CAVadjusts damper opening to secure the specified volume even when pressure inside the duct changes.
Normally inside duct:
➢ Highstatic pressure = Air Volume Increases
➢ Lowstatic pressure = Air Volume Decreases

What is VAV (Variable Air Controller)?

VAV is a device to keep air-volume constant no matter how pressure inside the duct changes. For those seeking to explore more about this theme, it is highly recommended to learn about ghostwriter bachelorarbeit.
VAV is designed to project required (nominal) amount of air by adjusting opening rate of damper blade even if the volume of air sent through duct increased/decreased.
➢ Send temperature room setting
➢ Control the Air-Cooling flowrate

Feature

• Accurate wind volume control function (equipped with high-accuracy digital wind velocity sensor and control circuit).
• Copes with severe room pressure control by diminishing lead-time required for opening/closing (fluctuation of air volume caused by operation lead-time is diminished).
• Digital wind-velocity sensor: small sized, shape does not allow dust to adhere.
• Simple structure minimizing numbers of mechanically movable parts (trouble caused by friction is minimized).
• Allows Max. 20 units in tandem operation.
• Low pressure loss and low noise.

Air Diffuser is a product which efficiently diffuses conditioned air in our living space(room).
Not only the performance aiming at creating the comfortable living environment but also a variety of shape & coloring selected in harmony with room interior is required.
Kuken Diffuser meets the diverse needs of customers along with high technical and production capability.
The Kuken diffuser dominates the market in Japan because numerous major buildings adopt it widely. Additionally, its exceptional performance and reliability contribute to its widespread use, making it the top choice for many architects and engineers.
We have obtained ISO9001 certificate in 2000.

We produce various kinds of Diffusers including Round & Square type ceiling diffuser, Nozzle, Linear, Floor-mount type, etc.
Comprehensive data analysis from actual laboratory testing guarantees performance. Furthermore, this thorough approach ensures accuracy and reliability, making the product dependable.

Feature

Damper is a disaster prevention equipment, installed in between duct or near Return Grille. For those seeking to explore more about this theme, it is highly recommended to learn about projektarbeit.
Damper is a product in which “Function” is considered as a primary option, not “Design”.
In addition to the standard Fire Damper, we have various types of dampers in a variety of application.
Lloyd’s (U.K.), ABS (U.S.), and NK (Nippon Kaiji Kyokai) type-approved dampers are also available.

We produce and distribute a various kind of dampers : Smoke Damper, Fire Damper, Smoke-Fire Damper, Relief Damper, Gas Pressure Damper and Volume Damper,etc.
All dampers are approved by Association of Disaster-prevention Equipment, Japan.

Cooling Tower is a kind of Heat-Exchangers to cool down heat medium such as water by contacting it to the atmosphere directly or indirectly.
We have been making progress as a leading company in the air-conditioning field since we granted our first patent for axial flow type Cooling Tower.
In addition to the Cooling Tower for air-conditioning application(overwhelming market share domestically), we have been supplying large-scale Cooling Tower for Industrial use to many plant facilities.
We also focus on the product development corresponding to the customer’s need with Low Noise,Energy Saving & Plume-Abatement type.

Open type Cooling Tower

Open type tower cools down the circulation water by contacting it to the atmosphere directly taking advantage on latent heat effect.

Compared to a Closed type, an Open Type features high-efficiency, compact in size, easier in maintenance, and lower in initial cost.

Development applying new technology brings high-efficiency

Tower becomes compact in size thanks to the newly developed Filling and Fan Unit.
Newly developed Filling minimizes drift-loss rate.
Further noise reduction can be expected due to Newly developed Fan Unit.
More durable in consequence of adopting the most appropreate metal parts with additional galvanizing.

Maintenance made simple

Inclined Lower Basin with Inspection Board, Internal Piping made maintenance & cleaning work simple.

Closed type Cooling Tower differs from an Open type in the sense that circulating water runs only inside a totally enclosed copper tube and it never contacts ambient air. Due to this fact, water quality control made simple.

Feature

High Protectability

Polluted air sucked into the tower, scale and slime generated by over-concentration and poor quality of water are attributed to be the cause of mechanical trouble.
It is not only the problem for cooling tower but also for the related equipments used in the whole system.
With Closed type cooling tower, whole cooling system is totally protected against water-related trouble.
