HISPEC

Standard specifications include 5 operation patterns

In addition to constant value operation and auto start function operation, 2-step pattern operation 1-3 are standard specifications. Each of these pattern operations can be set to repeat, and one-touch operation is all that is required for the second and subsequent operations.

• Regular operation (auto-stop operation)Operation: Constant temperature and constant time.
• Auto start operationAfter waiting for a certain period of time, it operates at a certain temperature and for a certain period of time.
• Pattern 1 operation: Operates at two different temperatures and times (not including temperature change time).
• Pattern 2 operation: Operates at two different temperatures and times (including temperature change time).
• Pattern 3 operation (temperature gradient operation)Operation with two types of target temperatures and temperature change times.

Overshoot eliminated when temperature rises

Unique temperature control PID control system enables precise control at any temperature setting. Overshooting during temperature rise is prevented and control performance is improved.

Easy setup and operation

• interactive interaction
  Setting items required for operation are displayed sequentially in an interactive format by pressing the menu key, and can be easily set by simply entering numerical values.
• Intuitive Graphics
  The control panel has a setting value input section on the right, and images connected by numerical values and symbols are collectively displayed; LEDs and pull-out lines make operation easy to understand and intuitive.
• Japanese display
  All displayed characters are in Japanese for ease of understanding.
• simple operation
  Four basic keys can be used to make settings with a few movements. Help display and guides make the interface easy to use even for beginners.

Setting value always displayed

The set temperature and remaining operation time are always displayed, allowing the current operation status to be checked at a glance.

Lightweight operation

Recessed operation keys, menu-driven setting items, and a bright, easy-to-read digital display provide a comfortable and enhanced operating feel.

Full range of included features

It is equipped with a full range of accessory functions, including a power failure recovery protection function, heater output monitoring function, and test termination output and trouble output.

• during a power outage: The set value and total time are backed up and not automatically restored (display alternates between the set temperature and remaining time).
• Heater output: Digital display of heater output during operation.

Abnormal judgment detection step

HISPEC monitors multiple temperature changes in the tank, and in the event of abnormal temperatures, multi-layered safety controls are activated, shutting off the heater circuit as necessary to ensure safety.

2. CPU Judgment
3. Temperature Setting Comparison
4. Over-rise and over-low judgment
5. Heater circuit ON/OFF control

Highly accurate temperature distribution performance by eliminating overshoot

In addition to an in-vessel structure that takes advantage of many years of chamber technology, the use of a propeller fan with high air volume greatly improves circulation performance. Excellent temperature distribution performance of ±1.5°C (±2.0°C for #40 type and above) and high stability are realized.

Functions can be switched according to purpose

The hot air circulation function and the unidirectional hot air exhaust function can be used separately by switching the ventilation damper on the front, lower left or upper left side of the main unit. This function can be flexibly adapted according to the sample and purpose.

Simple maintenance zones

The number of parts used has been thoroughly reduced to improve reliability in long-term operation. As a result, the number of maintenance requirements has been greatly reduced, and the reliability of the entire system has been further enhanced.

Unitization of heater section realizes cost reduction

ETAC's uniquely designed heater section is commonized with other models by unitization. Cost reduction and standardization of assembly processes are realized.

Space-saving design

The main unit is vertically oriented and the exhaust port is located on the ceiling. This saves space in the installation area.

Capable of heat treating many samples at the same time

Hot air circulation is forced by a sirocco fan, which ensures sufficient circulation efficiency even when the distance between specimens is relatively small, allowing heat treatment of many specimens at the same time.

Heater unit with excellent durability

Sheathed heaters are standard equipment, enabling safe and long-term continuous use even when a large number of samples are loaded.

Dial damper knob

The damper knob is a dial type, allowing the degree of opening to be determined at a glance. It is also equipped with a lock mechanism to prevent accidental operation.

Adoption of heat-resistant decorative frames for control equipment

A heat-resistant decorative frame is used to prevent adverse effects on control equipment caused by opening and closing the door, even during high-temperature operation.

Improved safety when opening and closing doors during operation

Opening the door during high-temperature operation activates the door limit switch and stops the circulation fan, preventing workers from being blown by the hot air.

Equipped with vents to exhaust wind pressure completely

A pressure-relief opening (vent) is installed in the ceiling. Venting is safe in the event of an explosion.

Safety-conscious structure

The exhaust section is securely covered to a height of 1.8 m above the floor. The door perimeter is equipped with a locking mechanism that makes it easy to open and close while maintaining sufficient strength.

Superior operability

Easy operation from temperature setting to start of operation provides an intuitive operating feel common to the series.

Discharge of vulcanized folded material to the outside

Fresh air induction and forced exhaust increases circulation efficiency, and treatment is performed without affecting vulcanized materials or external components.

Double swinging door for easy operation

Double-sliding structure reduces the opening radius to half. Improves productivity during high-temperature operations.

Easy-to-operate control functions

Auto start/stop/weight functions are standard, allowing easy operation with one-touch operation the next time.

Adoption of forced exhaust system

A forced exhaust airflow system is used to blow air inside the tank. Flammable gases generated in the tank are constantly exhausted to the outside, preventing their concentration from rising.

Gas concentration alarm as standard equipment

Equipped with a high-temperature compatible gas concentration alarm to monitor the inside of the test chamber at all times. It is equipped with a safety function that enables operation only when the gas concentration is below the lower limit.

People-friendly safety design

The door structure is designed for ease of operation and safety, with a simple locking mechanism and safety interlock. Equipped with an uninterruptible power supply, the ventilation continues for a certain period of time even during a power failure.

Equipped with safety structures throughout

Various safety devices such as explosion vent mechanism are standard. Special inner tank structure design ensures high safety.

Guaranteed residual oxygen concentration of 100ppm or less

It can stably reproduce residual oxygen concentrations of 100 ppm or less while reducing the amount of N₂ gas used to 1/5 of the conventional level.

Improved temperature lowering mechanism

Ability to lower temperature from 250°C with the door closed is 1.5 times faster than conventional units. Expands the workable area. If further shortening is required, a water cooling mechanism (optional) is available.

Temperature uniformity

Temperature distribution performance of ±3.5°C (at 250°C setting) is guaranteed. Improves heat treatment yield.

High performance and high precision

Reaches MAX500°C in about 60 to 70 minutes. Unique PID control suppresses overshoot and provides excellent temperature distribution inside the tank.

Designed with safety in mind

Triple safety mechanism against abnormal temperatures (over-temperature limiter, upper limit setting, and thermal fuse). Door lock mechanism and highly sealed structure with double packing for long time use.

Easy-to-use controller

The HT/HS series shares the same operation system with the HT/HS series, with 2-step programmed operation, auto-start/auto-stop, and each safety device operation display as standard features. Intuitive operation.
