Choosing Kesar Control Systems as Your Walk-In Stability Chamber Manufacturer in India
In the pharmaceutical, biotech, food, and cosmetic sectors, ensuring precise environmental control during stability studies is essential. When it comes to large-scale testing, a walk-in stability chamber is often the best option. If you’re evaluating a Stability chamber manufacturer in India, Kesar Control Systems stands out as a top choice. Here’s why, plus what to check when selecting a stability chamber, with specific reference to what Kesar offers.What Is a Walk-In Stability Chamber & Why It Matters
A walk-in stability chamber is essentially a large enclosure where scientists can enter to conduct tests under controlled conditions of temperature and relative humidity. These are particularly useful for:
- Stability testing of large batches of pharmaceuticals under ICH / GMP conditions
- Shelf‐life / long-term storage assessments in food, chemicals, and cosmetics
- R&D labs where frequent access and handling of samples is required without disturbing environmental stability
Accuracy, uniformity, safety, and reliability are critical. The best manufacturers deliver consistent performance, robust build, and dependable support.
Why Choose Kesar Control Systems
Kesar Control Systems is one of the leading manufacturers of walk-in stability chambers in India. Their product is well-suited for stringent regulatory and research needs.
Here’s a breakdown of what makes their chambers strong contenders:
Key Specifications (What Kesar Equipment Delivers)
- Temperature Range: 20 °C to 60 °C ‒ this covers most stability test profiles.
- Humidity Range: 40 % RH to 95 % RH ‒ ideal for many pharma/ICH stability conditions.
- Accuracy: ± 0.5 °C in temperature, ± 2.0 % RH in humidity.
- Uniformity (how evenly conditions are maintained): ± 2.0 °C & ± 3.0 % RH.
- Test Profiles Supported: Common ICH combinations like 25 °C / 60 % RH, 30 °C / 65 % RH, 40 °C / 75 % RH, and others. Also, special low-humidity profiles like 25 °C / 40 % RH, 30 °C / 35 % RH are accommodated.
Construction, Features & Safety: Kesar’s Strengths
- Modular Panel Construction: Prefabricated panels with PUF insulation allow for assembly on site, which helps logistics and ensures good thermal/humidity sealing. Floor panels are reinforced to handle movement and loads
- Interior Finish: High-grade stainless steel interior (water & vapor-tight) for durability, hygiene, and easy cleaning. External surfaces: either stainless (for GMP models) or GI with powder coating for standard models.
- Observation Windows & Racks: Multi-pane vacuum-sealed glass windows let you view samples without disturbing conditions. Trays are stainless steel, electro-polished, adjustable, and easy to clean.
- Control & Monitoring System:
- 7-inch HMI (colour touch screen) with password protection.
- PLC control, with auto-tuning for both temp & RH.
- Imported 4–20 mA sensors for better accuracy.
- Data storage in both HMI & PLC; data export via USB/Ethernet; PDF reports; event logs.
- Safety & Alarm Features:
- Door access security (password-protected) + logs of who opened/closed.
- “Person trapped” door safety / cut-off facility, so inside safety is ensured.
- Alarms for temperature & RH deviations, power failure, and low water level.
- Prevention cut-off for extreme temperature/RH.
- Continuous open-door alarm. Auto changeover for humidity generator & cooling system.
- Optional Enhancements:
- Stand-by cooling/humidity systems, online monitoring (scanners recording multiple points of temp/RH), GSM alerts, security alarms.
- Software compliance for audit trails, e-records, and e-signatures (21 CFR Part 11) for regulated labs.
Matching Your Needs: What to Look For (Using Kesar as Benchmark)
When you evaluate walk-in stability chambers (whether from Kesar or others), ensure you check the following:
- Desired Temperature and Humidity Profiles Make sure the chamber can achieve both high and low extremes needed for your tests. Kesar covers many common ICH profiles and also supports low-humidity conditions.
- Uniformity and Accuracy Tolerance Tight tolerances help reduce the risk of out-of-spec results. Kesar ensures ±0.5 °C accuracy, ±2 % RH accuracy, with uniformity of ±2 °C and ±3 % RH.
- Build Quality and Finish Look for chambers with stainless steel interiors, proper insulation, durable door seals, and sturdy racks. Kesar provides SS interiors with reinforced flooring and modular panel construction.
- Access, Safety, and Alarms Prioritize user safety and product integrity. Features such as alarms, person-trapped safety cut-off, continuous door-open alerts, and password-protected access are standard with Kesar.
- Traceability and Data Logging For regulated industries, audit trails and data logging are essential. Kesar offers HMI/PLC-based systems with USB/Ethernet export, event logs, and 21 CFR Part-11 compliance for secure records.
- Size and Capacity Options Ensure the chamber size suits your testing volume. Kesar provides a wide range of capacities, from 2,400 L to approximately 24,000 L, with customization available.
