E-Val Pro Introduction

  • The E-Val Pro Thermal Validation Cable System is a 4-40 channel system designed for validation applications that require compliance with the FDA guidelines and international GMP standards.
  • The E-Val Pro system has a full audit trail as well when using the stand-alone function. The ValSuite® Pro software keeps a complete database on all aspects of validation requirements – tracking probes and sensors, calibration reports, test setup, data analysis, specific user
    access, and final compliance report.
  • The E-Val Pro Module operates on OS Windows CE version 7. If only one E-Val Pro module is in used, the module can be operated as a standalone unit – or be directly connected to the computer by USB or Ethernet port using a standard LAN cable. Upon using more than one EVal Pro module, an Ethernet switch or USB Hub is required

E-Val Pro Module

  • The E-Val Pro Master module is a small, user friendly, easy to operate, and very accurate measuring instrument. It is possible to configure and operate the module using the 8” touch display and its functions. The module can handle from 4 to 40 probes and the internal memory can store up to 11.520.000 total samples. These samples can be spread out across 10 smaller sessions of up to 1.152.000 points or be allocated into one long study of up to 11.520.000 points.
  • The sensors can be temperature thermocouples, digital pressure – or input signals for I/O, 4 – 20 mA or 0-10 V. To measure according to specifications, connect the probes, power up the module and operate the module by the touch display or by the ValSuite® Pro software installed on PC. The data points are stored in the E-Val Pro module memory as soon as a session is started – and transmits the data to the software once it is connected.
  • The Master module is powered by a 12 V DC power supply with a built-in backup battery in place. The E-Val Pro battery has an 8-hour capacity.
  • On the rear side of the E-Val Pro module, is an On/Off button. After pressing the On/Off button to start the E-Val Pro system. Once started all channels will be measuring within one minute. The E-Val Pro can be shut down through the Menu systems shutdown function or by pressing the On/Off button on the rear side. The On/Off button needs to be held down for 5 seconds to turn off the power

Module/Sensor array configuration

  • The Master module can accommodate one multipurpose, high power (100 mA/5V), 4 channel sensor array plus 1-3 low power (40 mA/5V) 12 channel sensor arrays. These arrays are delivered separately and are carefully mounted in the corresponding sensor array slots. This is done on the back of the Master module by removing the blind plate(s) once the power is completely turned off. After mounting, turn the power back on and the system will automatically initiate, allowing for the appropriate sensors to be connected.

Coin Cell Battery for the E-Val Pro Clock

  • The E-Val Pro is equipped with an in-built clock, which runs on a coin cell battery with an estimated lifetime of 10 years when the module is turned off. When the module is on, the clock will draw energy from the main power supply instead, providing a longer lifetime for the coin cell battery. This battery will therefore last for 10 years + the amount of time the E-Val Pro has been turned on.

Eval Pro Sensors

  • The E-Val Pro Module can be connected to 1-40 temperature probes as well as 4-20mA, 0-
    10V, digital pressure, rotation, or deflection sensors via the Array USB interface.

Temperature Probes
The E-Val Pro modules are designed for the Ellab premium grade type T, 7 strand thermocouples. The Ellab thermocouples are equipped with an electronic ID, allowing for easy identification of the thermocouples. The standard SS* probes are supplied with threads that fit into packing glands, forming a no-leaking seal into packages or cans.

The lethality function supports a default value of F0.
  • Heat Penetration: A heat penetration study is about determining the heating and cooling behavior of a product/package combination in a specific retort system for the establishment of safe thermal processes and evaluating process deviations, and to find the “cold spot” in the product/container, and to ensure that all products receive the heat scheduled. ValSuite supports the heat penetration method known as The Ball Method which refers to the formula in Thermal Process Time for Canned Food (National Research Council Bulletin 7, Part 1, No. 37 [1923]) document.

       Typical Use of Heat Penetration

       Calculation of heat penetration constants.

       Simulation which can be performed in the Ball mode.

  • Mean Kinetic Temperature (MKT): Mean Kinetic Temperature is used as a statistical analysis to check if product has been decomposed due to fluctuation in the storage temperature.
  • Advanced Phase Statistics: is a multi-flexible analysis tool that can-do statistics and limit tests on automatically detected phases in a process. Advanced Phase Statistics works with ValSuite Sensor groups which can divide the sensors into groups representing a location or temperature zones in a tunnel.
  • Electronic Bowie Dick Test: The Electronic Bowie Dick test report is used for daily routine control of sterilizers as well as analyzing sterilization processes.
  • Door Opening Test Report: The Door Opening Test Report is new to ValSuite 6.0, This is created according to the qualification methods: Test open door study in chapter: 14.4.3 Performance Qualification in Handbook of Stability Testing in Pharmaceutical Development (springer) ISBN: 978-0-387-85626-1. The overall purpose of this test is to provide a framework for temperature-recovery upon a door/hatch being opened and allowing outside air into the enclosure. This will affect the maintained temperature in the enclosure and the temperature will therefore need to be restored within an acceptable timeframe without also fluctuating outside the acceptable band.
