Description
Archive Classification – CE4 Dual Coil Tank (Ireland)
Archive Notice (Ireland 2026): This entry documents the legacy CE4 Dual Coil Tank format used in early refillable vape platforms. The component is preserved for structured historical reference within the Irish hardware archive.
Browse Clearomizers & TanksThe CE4 Dual Coil Tank represented a variation of the top-coil clearomizer platform incorporating dual heating elements within a single head assembly. This configuration aimed to increase vapor production relative to single-coil CE4 variants while retaining compatibility with eGo-style pen batteries.
The architecture relied on long silica wick strands extending from the coil housing toward the liquid reservoir. As a top-coil design, the heating element was positioned above the tank chamber, requiring consistent wick saturation during operation.
| Parameter | Specification | Usage Context | Technical Notes |
|---|---|---|---|
| Tank Type | Top-coil refillable clearomizer | Early refillable vape platforms | Transparent liquid reservoir |
| Coil Configuration | Dual coil head | MTL or restricted draw | Higher heat output than single-coil CE4 |
| Wicking Material | Silica fibre strands | Low-wattage devices | Pre-cotton coil era |
| Typical Resistance | Commonly within 1.8Ω–2.4Ω range | eGo-style batteries | Dependent on batch specification |
| Connection Standard | eGo / 510 threading | Pen-style compatibility | Legacy interface |
| Market Status | Legacy tank format | Archive documentation only | Superseded by bottom-coil and pod systems |
Market & Technical Context – Ireland
CE4 Dual Coil tanks were distributed during the earlier refillable device phase within Ireland. As hardware engineering progressed toward bottom-coil clearomizers, improved airflow design, and later compact pod systems, demand for top-coil dual-coil tanks declined.
While EU TPD regulations focused primarily on liquid container and tank volume limits (maximum 2 ml for refillable reservoirs), technological evolution rather than regulatory restriction led to reduced retail presence of CE4-style tanks.
Archive FAQ – Ireland
Q: What was the purpose of a dual coil in CE4 tanks?
A: Dual coils were intended to increase heating surface area and vapor output compared to single-coil variants.
Q: Are CE4 Dual Coil tanks compatible with modern pod devices?
A: No. CE4 Dual Coil tanks were designed for legacy threaded pen systems and are not compatible with sealed pod platforms.
Hardware components documented here were intended for adult users. Devices and nicotine-containing liquids are restricted to 18+ consumers in Ireland.
