Kagawa Electric Power Co., Inc. (Headquarters: 10-5 Tenjinmae, Takamatsu City, Kagawa Prefecture / Representative Director: Hiroyuki Miyamae) has developed "PitCube2," a cubicle specialized for auto repair shops, to meet the needs for new or updated power receiving equipment accompanying the introduction of air conditioning in auto repair shops. Orders will begin on April 1st, and shipments will start in late May.
PitCube2 inherits the concept of the conventional PitCube (specialized for auto repair shops, space-saving) while featuring a completely new design, including the transformer and electrical circuits (power supply design). It also comes standard with ground fault protection functions, enhancing safety, and the installed transformer complies with the 3rd Top Runner standard. The revamped PitCube2 will be shipped in as fast as 2 business days, achieving virtually immediate delivery. It solves the challenges of "insufficient power receiving capacity, difficulty in power supply design, and long lead times" that have hindered air conditioning installations in auto repair shops, addressing both product and supply system aspects.
PitCube2 is managed by Kagawa Electric Power Co., Inc. (development planning and unified sales contact), with transformer design and manufacturing handled by Daifuku Co., Ltd., and cubicle design and manufacturing by Kawamura Electric Corporation. In response to the background where increased demand for cubicles led to supply shortages and unpredictable delivery times, delaying decisions on air conditioning equipment installation, PitCube2 standardizes specifications as a general-purpose type, achieving a "no more waiting" procurement model through the cooperation of the three companies.
Furthermore, Kagawa Electric Power goes beyond cubicle supply, offering nationwide support for air conditioning equipment procurement, air conditioning electrical work, and cubicle replacement work, from consultation to arrangement (※Utilizing a network of partner companies. Scope and conditions vary by project).
"Don't stop air conditioning work due to cubicle shortages." — Background: What's lacking is not the "equipment itself" but "delivery certainty."
Improving the working environment in auto repair shops through air conditioning installation is a crucial theme directly linked to maintenance productivity, heatstroke prevention, and the recruitment and retention of mechanics. However, in practice, even when plans for new or updated air conditioning are decided, cases where projects are halted due to unpredictable cubicle delivery times are frequent.
Individual design (ad-hoc design) and procurement of cubicles for each project lead to specification variations and complex arrangements, traditionally requiring several months for delivery. With the "3rd Top Runner Judgment Criteria for Transformers," effective April 1, 2026, which emphasizes requirements for switching to high-efficiency transformers, cubicle delivery times tend to become uncertain.
PitCube2 addresses this bottleneck by standardizing materials, assembly, inspection, and procurement as a "general-purpose type" specifically for air conditioning installation in auto repair shops. Furthermore, by incorporating supply design (a system that integrates inventory and production planning), it structurally achieves short lead times.
Product Overview: Compliant with the 3rd Top Runner Standard. Meets the "Prerequisites" for New Installations and Updates.
PitCube2 is a cubicle designed to comply with the 3rd Top Runner standard, meeting the prerequisites required for new installations and updates after April 2026.
It is provided with specifications that facilitate future new installations and updates, based on the concepts required by the 3rd Top Runner standard (e.g., achieving energy consumption efficiency targets / complying with the scope of specific equipment / conforming to eco-design guidelines / initiatives for CO2 emission reduction).
※Individual specifications are confirmed per project.
Features of PitCube2
1) General-purpose type = Low cost. Reduces specification variations and simplifies estimation to procurement.
By limiting its use to "air conditioning installation in auto repair shops (+gyms, etc.)" and standardizing it as a general-purpose type, it reduces the man-hours and adjustment costs of individual design, achieving a procurement model that facilitates introduction decisions.
2) Space-saving design. Can be placed / Predictable construction.
To increase the certainty of introduction even in sites with many installation constraints, emphasis is placed on space-saving design.
(Reference model) External dimensions W1180×H2100×D1145mm / Body dimensions W1100×H2050×D950mm (75kVA class).
It makes it easier to plan site搬入 and layout, supporting predictable construction.
3) "Make it in time for this summer's construction!" Virtually immediate delivery cubicle.
Since PitCube2 is standardized and manufactured as a general-purpose type, it can be shipped in as fast as 2 business days after specifications are finalized (※Varies depending on inventory status, number of units, delivery area, and site conditions).
To achieve "immediate delivery," the three companies cooperate to aim for "no more waiting" procurement.
4) Ground fault protection function "GR・ZCT" as standard equipment.
Among the protection functions required for power receiving equipment, emphasis is placed on ground fault (leakage/ground fault accident) protection, with GR (Ground Fault Relay) / ZCT (Zero-Phase Current Transformer) installed as standard. This enhances protection and safety in site operations.
※Protection coordination and settings are individually confirmed based on system conditions.
5) Not just cubicle supply. Nationwide support for air conditioning equipment procurement, air conditioning electrical work, and cubicle work.
Air conditioning installation success depends not only on equipment procurement but also on execution capabilities, including power supply design, construction, and process coordination.
Kagawa Electric Power, in cooperation with its partner company network, provides nationwide support for air conditioning equipment procurement, air conditioning electrical work, and cubicle replacement work, from consultation to arrangement. This enables one-stop progress for site introduction (※Availability and conditions vary by project).
6) Quality from leading domestic manufacturers, reducing supply risk.
Transformer design and manufacturing, and cubicle design and manufacturing are handled by leading domestic manufacturers, clarifying quality, inspection, and accountability.
This reduces the risk of site introduction not only in terms of delivery but also for the entire procurement process with a reliable system.
