OSC Modular System
Feature of OSC method
It refers to a de-site production system, which is a construction method that maximizes industrial efficiency by diversifying production systems away from the existing field system.
Our modular products are composed of systems optimized for the OSC method, which facilitates the installation process and allows quick installation.
Innovatively improve the quality of construction (construction quality) by organizing key equipment and parts into standard modules in advance,
It is the latest construction method that realizes construction cost reduction and air reduction.

Optimal design
When selecting each component, it is designed in consideration of each control characteristic so that the performance of the entire heat exchange facility can be smoothly displayed,
thereby achieving an optimal design that maintains the balance of the configuration period. - Factory manufacturing It is manufactured, assembled, inspected and tested in the factory, so it has excellent construction quality and appearance.
- Prehab Construction Method Since piping and welding work in the field is minimized, air can be greatly shortened.
- Compact design The installation area can be reduced by more than 50% by optimal device placement.
- Construction cost reduction Simplification, standardization, and specialization can maximize productivity to minimize construction costs compared to quality and performance.
- Energy efficiency improvement The overall energy utilization efficiency is high because the control performance is excellent and the linkage of each component is smooth.

Responsible construction and performance comprehensive guarantee
Compact facility unit manufacturers guarantee quality and performance during the facility's life cycle, such as design, manufacturing, installation, operation and maintenance,
and support customers, so the limit of responsibility is clear, and construction companies can easily manage and supervise on-site construction.

Vertical Pump
It is designed in an in-line structure with the same suction and discharge diameter of the pump and is located on a straight line for water supply and pressurization facilities, and when a variable frequency drive(XQ·NSQ-Drive) is installed, it minimizes energy consumption by adjusting the pump's rotation speed according to the flow rate and head change.
Horizontal Pump
Horizontal Multistage Pump
Designed for household and industrial water supply systems, it is equipped with mechanical seals, pumps, and major shaft penetrating motors.
The main parts of the immersion are made of stainless steel and are durable.
Horizontal Singlestage Pump
The pump's suction and discharge ports are 90 degrees for water supply, pressure, and circulation, making it easy to disassemble and repair without disassembling the pipe
after the pump is installed, and the main parts of the inlet are made of stainless steel and are durable.
Fire Fighting Pump
A pump used to extinguish a fire, and a pump with specifications in accordance with fire law regulations must be used.
Fire Protection Act Regulations
The shutoff pressure of the Fire Fighting Pump should not exceed 140% of the rated discharge pressure so as not to strain the pipe due to excessive pressure rise of water,
and even if the amount of waterproofing increases by using multiple hydrants simultaneously, the water pressure should decrease and the fire should not fail.
Therefore, the pressure should be at least 65% of the rated discharge pressure when operating at 150% of the rated discharge.
Selection criteria for Fire Fighting Pump
Key Point
- Satisfy the flow rate and head of the specification point
- Shutoff head should be less than 140% head of the specification point
- At 150% flow rate of the specification point, the head should be 65% or more compared to the head of the specification point
In-line Circulation Pump
It is mainly used in cooling and heating systems, industrial processing processes, and systems. The pump is designed in a top-pull-out method,
allowing the pump head (motor, impeller) part to be maintained without separating the pump housing from the installed piping.
It is also equipped with a variable frequency drive(XQ·NSQ-Drive) that can be used as a speed-controlled inverter pump.
There are three main types, DP In-line pump, Inverter pumps capable of controlling speed by installing a variable frequency drive(XQ·NSQ-Drive) on a single DP,
and Turbine In-line pump DPXL that are made of stainless steel to ensure clean hot water supply without rust, and a cast-iron DPX model.
Controls and Monitoring
It is a system that is mounted on a pump to provide pump control and energy saving,
It is largely classified into four types: Variable Frequency Drive, Controller, TM, and Internet Modem.
Variable Frequency Drive
An inverter that controls the speed of the motor and a controller with built-in operation and protection of the pump are integrated into one to fully control the operation
and operation of the pump without a separate control panel.
Automatically adjust the operation speed of the pump according to the fluctuation of pressure to
keep the discharge pressure constant and reduce unnecessary operation to significantly reduce energy consumption.
Controller
An economic pump control system with built-in pump control and protection functions.
TM (Monitor)
An integrated monitor that allows users to check the status of the pump by receiving each pump operation information stored in each inverter.
It is expressed as a full color display using icons to make it easier to understand various information such as operation details and alarm details.
It is equipped with a UX that is easy to use and a GUI that significantly improves user recognition rate and operability.
Internet Modem
A modem dedicated to a booster pump that connects the booster pump system to the cloud server to transmit collected data or to transmit operating instructions
generated by the monitoring system to the booster pump.
