Keram (Nanjing)ELECTRICAL Equipment Co., Ltd.

Company Overview

Introduction

Founded in 1998 as Keram Equipment Co., LTD, KERAMCONTROLS launched as a specialized manufacturer of pressure control products—laying the groundwork for its growth as a trusted player in the industrial components space. By 2005, the firm had expanded its portfolio to three distinct product lines, surpassing $100,000 in annual sales: a milestone that highlighted its growing market relevance and ability to adapt to the evolving needs of industrial clients.

A defining expansion followed in 2006, when the company moved operations to Huai’an Industrial Park (Jiangsu Province) and added a dedicated production line for heating system equipment—broadening its capabilities to serve a wider range of industrial and commercial heating requirements.

In 2009, KERAMCONTROLS entered a strategic joint venture with a leading German enterprise: aligning its manufacturing processes with rigorous German quality standards, expanding its heating equipment offerings, and cementing its reputation for technical excellence and reliability.

In 2014, the company re-branded as KERAMCONTROLS CO., LTD and relocated its headquarters to Nanjing—a move to enhance regional market access, streamline operations, and position itself for broader domestic and international growth. Building on this momentum, 2020 saw significant investments in sensor /transmitter product technologies: reinforcing its commitment to advancing performance, energy efficiency, and sustainability to meet the demands of modern industrial and commercial stakeholders.

In 2025, KERAMCONTROLS will establish a dedicated research and development center, focusing on the innovative research and development of sensor-related products.

Rooted in its core values—Customer First, Quality-Oriented, Keep Innovating, Dedication, and Faithful—

With a global design concept, KERAMCONTROLS is committed to becoming a high-quality supplier in the industry, providing industry-leading and highly reliable solutions, fostering long-term strategic partnerships, and adhering to the highest operational integrity standards within its global business scope.

	This is our company headquarters located in Yuhua District, Nanjing City. We have administrative, sales, and R&D teams to provide support for product production.

Our Capabilities

Production R&D

Production Line

Keram (Nanjing) Electrical Equipment Co., Ltd. is dedicated to providing stable and reliable industrial electrical products through scientific management systems and continuous technological investment. Our core capabilities in production and R&D are outlined below:

Core Capabilities

Production Management: We implement standardized production workflows integrated with an advanced Manufacturing Execution System (MES) to monitor production progress and process parameters in real-time. Through refined scheduling and on-site management, we effectively enhance production efficiency while ensuring the timeliness and consistency of product delivery.
Product Testing: We have established a comprehensive quality control system supported by a professional physical and chemical laboratory. From raw material inspection to finished product shipment, we strictly enforce multiple testing procedures. Key performance indicators suchs as pressure resistance, flow rate, and temperature are rigorously verified to ensure all products meet industry standards.
Warehouse Management: We adopt an information-based warehousing management model, enforcing strict batch management and shelf-life monitoring of materials. By optimizing inventory structures and logistics processes, we achieve accuracy and efficiency in material turnover, providing stable supply chain support for the production line.
Personnel Training: We maintain a regular mechanism for skills training and assessment. Employees receive ongoing training in professional skills, safe production, and quality management systems. This continuous improvement enhances the team's technical proficiency and quality awareness to meet the demands of modern manufacturing.

We will continue to uphold the business philosophy of "Global Design Concept, Reliable Quality Supplier" continuously optimizing our management and R&D capabilities to become a trusted partner in the field of industrial automation

R&D

Keram (Nanjing) Electronic Equipment Co., Ltd. has been focusing on the sensor field for many years and has established a relatively solid R&D system for products such as pressure sensors, temperature and humidity sensors, pressure switches, flow switches, wind speed and air volume sensors, and air quality sensors.

R&D and Testing Capabilities

The company currently has 8 R&D personnel, among whom core members possess over 20 years of experience in sensor technology and electronic engineering. The team's division of labor covers hardware design, embedded development, algorithm optimization, and reliability testing, allowing them to independently complete the entire process from sensor element selection to complete machine solution design. The company has also established standard environmental laboratories and pressure calibration equipment, including a self-developed wind tunnel test platform, multi-functional integrated test benches, as well as calibration devices from WIKA, ConST, and Kunming Dafang, capable of conducting conventional temperature cycling, humidity endurance, and pressure accuracy tests to meet basic product validation requirements.

Design Philosophy

The design team consists of about 3 people, advocating a work approach of "practicality first, refined details." In terms of exterior design, the focus is on usability in industrial settings, such as adopting standard threaded interfaces, clearly labeled terminals, and reverse insertion prevention structures. Some models have passed IP65 protection rating certification, and enclosure materials are primarily aluminum alloy and engineering plastic, balancing cost and durability.

Product Performance & Features

Regarding product performance, pressure sensor accuracy is controlled within 0.5% FS, temperature and humidity sensors have a temperature error of approximately ±0.5°C and humidity error of ±3%RH, and response speed meets conventional industrial monitoring requirements. For functional development, it supports mainstream output modes including 4-20mA, RS485, and Modbus protocols, and can adjust measurement ranges or add on-site display modules according to customer requirements. Wind speed and air volume sensors offer two measurement principles—thermal anemometer and pitot tube—to suit different installation environments.
